Thanks Gary. As always, I find all of your videos very informative. One quick question on this one. I find it hard to read the answers when in daylight mode on my Mac, being the answers are shown in a light orange on a white background. Is there any way to change the answers of the calculated total to a different darker color other than the default color?
Conversions using gallons are very useful when working out the costs of running a car. But I wonder if it only handles US gallons, or whether it will do Imperial gallons in the UK.
Excellent video, as always. Notes will autocomplete a suggested unit for conversions, such as quarts to liters. Is there a way to force a different destination unit? Suppose, for example, I wanted to convert fluid ounces to gallons (the default new unit is liters)?
Math Notes doesn't do that. This was never available in Notes. Tables in notes are just for formatting, and don't support calculations. But you can do it in Pages, and of course Numbers.
@@macmost Ok, But with respect, early on this was available in Notes with tables. I used it. Although it was short lived, it did allow you to sum up a column, by including the keyword SUM() in the last row.
Try it and see. Standard dictation didn't work, but maybe Voice Control dictation? Play around with phrasing. Experiment. I was about to say "2+3" and then type = and return and it worked. Not sure if that would help you.
the ~ function seems to have the following rule: the second number has no impact on the result, and if the first number is n, then n~.=n x (1+2+2^2+2^3+...+2^64). I don't know what it is used for.
I'm sure now it is a bitwise NOT. So imagine 64 bits, with the value of the number before the ~. Then invert 1s and 0s. So the number one is 63 0s and a 1. But 1~ is 63 1s and a 0.
It doesn't seem to cascade variables though? eg x=2 , y=2x, p=2y , now change x & p won't change. That's a tragic shame - otherwise it would be a great replacement for a lot of simple spreadsheets used to evaluate a set of formulae
It just doesn't update automatically. If you have tow lines: a=2 b=5a Then on the third Lind you type c= and return, you get c=10 But then you change a=2 to a=3 and nothing happens to the c= line. But if you erase the =10 after the c and type = and return, it does it. I've also seen it update when you leave the note and return to it, but not all the time. A refresh menu item or keyboard shortcut would be nice.
Not sure what you mean. Filters in Numbers hides rows of a table based on criteria. But in Math Notes you don't have tables or rows. Maybe take a step back and explain what you want to do.
I have a spreadsheet in Apple Number. Unlike MS Excel and Google Sheets Apple Numbers doesn’t have “FILTER” function which I want to use to perform a task.
@@gajendrajangid7789 What task though? I can't help without knowing what you are trying to do. Since this is getting off-topic here, ask at macmost.com/ask and I'll see if I can help.
The tilde symbol (~) in math can have different meanings depending on the context: 1. Approximation: It is often used to indicate that a number is approximately equal to another number. For example, π ~ 3.14 means that π is approximately equal to 3.14. 2. Proportionality: In some contexts, it represents proportionality. For example, y ~ x can mean that y is proportional to x. 3. Asymptotic Behavior: In calculus or higher-level mathematics, the tilde can indicate that two functions have similar growth rates as they approach a certain point. For example, f(x) ~ g(x) means that f(x) and g(x) behave similarly as x goes to infinity. 4. Equivalence Relations: It can also be used to represent an equivalence relation. For example, a ~ b means that a is equivalent to b in some specified way (e.g., congruent modulo a number). Its exact meaning depends on the field of mathematics and the context in which it is used.
@@macmost I am a Microsoft Excel user, so I use those Excel formula functions a lot. As shown in your video, it does look like we are entering a sort of formula functions like in the Excel, that is why I said that.
Ok so how on earth do I copy an external link to an apple note? Its driving me crazy. I simply want to put links to my own notes in my own calendar, reminders etc. No I don't want to share it to reminders. I want the link to the note.
@@macmost Wow great workaround! And you're right, I won't need that a lot, but I do need it occasionally. In the past notes have had a "copy link" button when you clicked share. Why did they remove that? Thank you!
That was by far the best explanation of Apple Notes Maths that I've found anywhere, thank you so much, we're living in exciting times! love it.
Agree 100%, I can only Like this video once, but I'm sure I'll be back to watch it multiple times. Well done!
Thanks for another awesome video!
The ~ is a bitwise operator for inverting all the bits in a number.
Thank you so much for your ever great work, Gary.
Thanks very much, Gary, for tihis informative video! These new maths functions will be incredibly useful.
Thank you very much for the presentation. The features presented look like those of the Qalc application in VSCode.
God bless Gary for this video!
Excellent tutorial. Very comprehensive. Many thanks!
This would have been sooo useful while I was in college. Really impressive.
A very useful and informative video tutorial today! Thank you, Gary! 👏🏻❤️

Conversions using gallons are very useful when working out the costs of running a car. But I wonder if it only handles US gallons, or whether it will do Imperial gallons in the UK.
You could just try it... and see that it does work. For instance, type "1 uk gal=" and you'll see.
Hey, thanks for the video. How did you change the number of decimal places for your answer? Currently, my notes app only gives me three places
I don’t think I set anything special for that.
Great video
Excellent video, as always. Notes will autocomplete a suggested unit for conversions, such as quarts to liters. Is there a way to force a different destination unit? Suppose, for example, I wanted to convert fluid ounces to gallons (the default new unit is liters)?
Yes. I show that in the section on Unit Conversions.
@@macmost Ah, use the ‘in’ function. Very nice. Thanks, Gary.
This is fab video really good tips
Great overview. Did you try vector math? Couldn’t get that to work.
I don't think there is anything to support vector math here.
thank you
It's like Numbers without making a spreadsheet.
On a Mac, can't you just use the Grapher app if you want to graph an equation?
Sure.
How about math (sums) in tables? i.e.: sum of columns... This use to be available in Notes tables but got taken out. Is this currently possible?
Math Notes doesn't do that. This was never available in Notes. Tables in notes are just for formatting, and don't support calculations. But you can do it in Pages, and of course Numbers.

@@ajimenez251 I must have totally missed that then.
Is there any list of available functions?
None. This may be as close to that as anything.
Thanks @macmost - subbed.
but can you also sum it all up at the bottom? for example
4+4=8
2+1=3
total = ?
You could do:
a=4+4 = 8
b=2+1 = 3
a+b = 11
But it sounds like what you really want is a spreadsheet.
Can you use dictation?

Yes, but what is it in Math Notes? That's all that matters here. It seems to be a bitwise NOT operator, which is not very useful for most people.
@@macmost yes
Yep I agree. I don’t see where I personally would ever use it.
Are they planning to give up the "Numbers" app soon?
Why would they do that? It is a powerful spreadsheet app that a lot of people love and rely on. And they keep adding new features to it.
@@macmostyou didn’t get it, he/she is trying to say that they put a lot of Numbers functionality into Notes app.
@@elalemtubeit's not 'numbers functionality'. It's 'calculation functionality'.

Does the calculator abide by the BODMAS rules that mathematicians use?
Order of operations? Yes. Try it and see.
