It's not as big as the original...☹️
I thought multiplication in binary was a lot harder. Enjoyed the video!
Easy
I did too!
Yes it is
Man you are a really good teacher. I'm not unfamiliar with CS stuff (M.S. in engineering, and have to program a lot), but you really make things just really straightforward and easy to understand, and I'm learning quite a lot. I'm passionate about effective tutoring, and you're quite inspiring. Every single one of these videos is a treat. Keep at it!
thank you :)
usually math gives me headaches but matt has added life and color to it.
Math with matt!
Your explanations are very good👍
I never realised that binary multiplication was so easy
In my University math classes calculators aren’t allowed. At least in the easier classes that I take. This video taught me a much easier way to do multiplication on paper/in my head. A big long multiplication problem is way easier when you just either do the top number, or nothing over and over.
Wow didn't know binary multiplecation is that simple, cool!
*multiplication
I know this video is about Multiplication and not about displays but I’ve an idea(some other people also already had this idea). Why won‘t build displays with maps, I mean it would be genius because Maps can have different scales, so you can have for example on stage 2 or 3 for one Pixel on the Map more Space, because one pixel on the map, would represent a area of let’s say, 4 x 4. But as I know, not the entire 4 x 4 Area would be used, only one specific Block of this area would be used. This technique, would allow you to build a real display, which would only be 1 Block big for the user. You could put a Map on the Wall so the user does not need to look at a very big screen. There’s also another thing which this technique would allow, you can make use of coloured displays because for every pixel on the screen, the contraption behind it can make use of an 4x4 area from the ground to the build limit(if you want so). I have also already done some research on the internet, there isn’t much about it but I’ve found one guy on PlanetMinecraft, who already had the same idea as me and built a 16-Color 32x32 Pixel Minecraft Map Display. It was originally build in version 1.12.2 but I’ve tried it in 1.15.2 and i think it should also work in Higher Minecraft Versions. It would be awesome if you try it, no you need to… I think this technique has a lot of potential and you should give it a try. Thank‘s! As I was Searching for this, I found more Displays, already with display controllers…
Easy without any kind of controller: www.planetminecraft.com/project/color-display-5411719/

These are the type of tutorials we need on TH-cam thank you matt
T perm
This is an amazing serie! You are so great, I learned so much. I subscribed. Can't wait for more!!!!
Which type of multiplier is your favorite and why? :o
I'm not sure just yet. But, I noticed that combinational so far just brute forces it, while sequential is a lot like pen and paper.
My favorite multiplier is any that multiplies numbers by my iq. You see, theyre super simple, as multiplying anything by 0 is 0
the mattiplier
The sequential one. I'm going to try to make an 8-bit version of it :)
hi, if I understand correctly, the combinational multiplier is faster, right?
I spent an hour trying to figure this out and then you came out with the video explaining how. Thank you
I’m very glad that I have worldedit lol
I LOOVVEE this series!!!
This is soo good!!! Great job!
Thanks for the content, very useful!
Binary multiplication sounded scary.. until I saw this :] NIce job, keep up the good work!
This is some amaazzing stuff!!!
matt's content is soo high qality :) proud to be here before 100k
i needed this so much
Really helped me in my project!
neat. thanks for sharing
nice best tutoriel in space of video presentation and addeting out ther keep it up even if it taks more time.
0:13 yo I am in this video lets gooo
Lollololololo
The second one is so cool!
Can't wait for the division video, so I can finish my own calculator project ^^
like ik that multiplication is just repeated addition but somehow this is even simpler than that in binary, so cool
Very good tutorial for my purpose.
awesome! what an amazing videos
So amazing! U are amazing!
u have the best voice for this
I built this exactly as shown in the video but it just flashed on and off repeatedly on certain lines. The accumulator itself worked perfectly, but the full thing with control circuits and everything was just flashing repeatedly.
Thanks, with this logic, i used my adder to make 8bit multiplication. nice video
How can you please tell me
@@artwithraman i have a tutorial in my channel, but it is in portuguese
@LucasBazan Can you provide me link I am having hard time to find it
@@artwithraman ok, here is the link: th-cam.com/video/ntWH97xU9Zc/w-d-xo.html (tutorial realy starts in 3:23, link goes to this momment)
But there are some "problems":
-it's not a cca adder that I used (so it varies the ticks in each calculation)
-the video is in Portuguese (and it's not the best video, as it's a little bit old).
-it's in the bedrock edition (probably doesn't work in java, because of redstone blocks above or in diagonals of pistons and glass towers going downwords)
Ohh. I am actually a bedrock edition player and I am building a calculator
Awsm video
I wrote same thing in your discord server about multiplication :)
Why are you saying you weren't satisfied with this series? You didn't need a LRR, this is awesome! Just came back to it cuz I needed your explanations, and my opinion hasn't changed since you published this video...
I have never been more confused in my life :)
Good video though
are you going to be doing a video on division as well? that would be great
Yooo new upload.
Have you heard of ternary logic? I've been messing with the concept using redstone signal strength. I can't find any layman-oriented information regarding ternary logic circuits, though, so all the gates I've made have been from trial and error, and they're very slow lol.
i haven’t heard of it being used, no, but you can do stuff in any base 2-16 using signal strength. but boolean logic is only possible in base 2, which is also what redstone is designed for, so i’m not sure why ternary would be useful
@@mattbatwings It's not necessarily useful, I just find the concept to be fascinating lol. And yes, redstone is definitely binary-oriented. Even making a ternary NOT gate was pretty complex, at least for me. 2=0, 1=1, 0=2. The middle state doesn't flip. Pretty weird.
@@Nae_Ayy Ternary is extremely useful. You obviously know nothing about circuits, voltage and anything outside of binary.
@@elitesniper4017 Yeah no shit nerd, get a hobby
I tried to make my own version of that second multiplier about a year ago, where the input goes in, then the output feeds back into the input until the answer is calculated etc but I wanted to do it only using what I knew at the time, the adders I knew how to make which were ripple carry, and not watching any tutorials for "the challenge", and I kinda got one working, but it was super janky and only worked like half the time lol
Before I watch the video, this is how I think the binary multiplication will happen.
1. take the top number, convert it to binary
2. take the bottom number, convert it to binary
3. every time a 1 appears in the bottom number, mark it on the answer row
4. replace every 1 on the answer row with the top number, and add them up
Hmm.. Does that means the sequential design is slower than the combinatorial? So it trades speed for simplicity, right?
Thank you for making these tutorials!
yes exactly
Now I want to do this. I have a 10hz adder that could make a multiplier with twice the bandwidth.
You can make a binary multiplication machine using and gates as multiplication.
Can you please make video about input platform (where you type numbers, what to do(multiply, subtraction, addition) itp.) ?
I saw some videos about “analog” calculators that use signal strength to compute in base 10 and don’t need to convert from binary to BCD and stuff… Are they any faster than normal binary Minecraft calculators? Can they do everything normal ones can do?
I play on playstation 3 still. granted some of the redstone is different. I've had to change the CCA due to lack of target blocks-very simply change though. Anywho, I built each of these by hand and oh boy i can speed run an 8 bit CCA now. I know each block and its purpose like 1's and 0's XD. A lot slower than commands or world edit. Although, definitely ingrains the meaning of each piece of redstone in the build.
since i had to build it differently, my CCA is 10 gt (i automatically convert redstone ticks to game ticks. Learned it from Matherzzz i think). then I had 2gt 4gt 4gt repeaters. 20gt (9:30 ish) I had it timed for 1 cycle per second. took me forever to find that at the very bottom. the value taken. it doesn't go through comparators unless you have a carry in (we don't). so it had 2 gt less than supposed to. Although, i'lk never make that mistake again!
we have a carry in now (2 seconds after i said we didn't)
This is awesome! I’m personally trying to build a calculator using your vids. I’m stuck on BCD to binary because certain numbers don’t work like 107. It gives me 103 instead since the carry in on 4 is already active. Any ideas how to help?
personally I use a serial double dabble algorithm, can be used in both direction (encoding and decoding). all you have to do is to build an encoder & decoder then hook it up with some memory to save the shifted result
no carry issues because the main engine is a decoder
maybe just look for double dabble algorithm on Wikipedia, also there are awesome tutorials to do it in minecraft
Yaaaaaaa
Is there a better multiplying method that doesnt make the adder bigger or longer?
can you do a video about dividing in binary?
I know I'm late on this, but how would you take an output from this decode it, and plug it into a customizable display? I'm working on a calculator and I have it encoded to be able display 0-9 on both digits of the sum. (I have a 4-bit calculator, so number 1 can be 0-9 and number 2 can be 0-9 and the sum can be 2 digits) I dont know how to controll both digits of the sum independantly and encode to them from the multiplier. If someone could help me that would be appreciated!
If we implement the vedic maths logic, it would be easy to design in redstone
Just a question, why would you opt for the sequential design? It seems more complex, more difficult to troubleshoot and slower than the combinational one. I guess it's more compact but that shouldn't matter too much.
trust me if you make a 8bit combinational multiplier it would be ENOURMOUS.
Helppp...
Why can't the accumulator clearer don't work well on mine
The problem is it keeps all of them lit and the lowest keep turning on and off😢😢😢😢
fun fact. 4 bits is called a nibble
22 bit multiplier here i come
I'm guessing that to make a 8 bit multiplier you would have to use a 16 bit adder /s
So... I just spent about two hours trying to understand what I had done wrong while building the sequential multiplier until I realized that I had to put the repeaters locking the blue circuit on 2 ticks instead of 1...
im gonna use an full ader and a shiftregister like a maniac
I want an 8 bit sequential design
Aye
first :troll face:
When i built one it kept on flashing after the calculation was complete (sequential one)
if i hook the following contraptions: addition subtraction multiplication division to a display will it turn into a calculator
yes but you should figure out BCD displays and other features to make it easier and more efficient to build. but by definition it will be a calculator with just those 4 things
How would you get past the signal strength problem to make a 16 bit multiplier
same question
Ok i got something funny, i built the CCA from LLR in bedrock and its 1 tick faster for some reason? So I'll have to do everything you do tick-wise minus 1. Funny times.
Idk y but When I do something it blicks with 2 random Bits i have checked the timings and they work
@mattbatwings how would i make the blue without target blocks (10:50) *Praying Emoiji* --- Edit: silliest question ever. It's obvious. Target block=redirect redstone. just move redstone over 1
What mod for the editing? Copy and paste, expand, stack
it’s called “world edit” , i have installed it using forge and it works great
Are you playing on bedrock or Java?
Is there an easy way to make the sequential 8 bit? i am making an 8bit claculator and it is 8bit.
You should just need to add more modules to the top of the one in the video
Hey!
Did u find an 8bit version?
I tried to build one but I dont get it
@@tomfuchs8584 Yes! bennyscube has one here: th-cam.com/video/phoDdy5rrGs/w-d-xo.html
not shore but since it’s eight bit, the result will be 16 bit max so you would have to stack an 8 bit CCA on top of another one, remember to repower all the slab towers (even the ones contained in the CCA) as the signal goes only 15 blocks, from there just do everything twice, hope it helps 👍
What zoom mod do you use?
okzoomer
@@mattbatwings that is the best name i have ever heard
Have watched your entire series. As a dad I would pay money for this sort of content for my kids. Ever considered Udemy Orr Skillshare?
thanks for watching the series! i have considered it, but i’ve always felt under qualified, cuz a lot of this stuff is what i’ve figured out only through experimenting. perhaps i’ll start it next year after i’ve taken a lot more proper compsci courses
Does anyone know how to make the sequential one 8 bit?

@@wil942 K thx
there's no "multiply" command in Minecraft, ITS REALLY NEEDED FOR ME AAAA
🤔
But some multiplications like 7×7 is 64 and 9×9 is 80 and 3×3 is 8 ,why
What is the thumbnail?
😢it doesn't work into bedrock version😢
Why don't people just do everything in binary? It's sooo much easier!
Im doing it withput world edit 😭
RIP
nnow i will start multiplying in binary since i dont have to remember all multiplication tables from 1 to 10
good luck multiplying numbers bigger than 64
But the problem is.. I need a 15 bit
first
This is why I love your channel!! You could get the engagement you deserve with P R O M O S M!
UwU
I'm Gonna watch this later, I kinda wanna try and design a multiplier first. (=
