you are such a kind-heart person...thanks for sharing. Intuiation and engineer living under one roof
3:06, my brain turned off what is this number 100 with B2?
wow that was explained so much simpler that i understood it immediately! thank you very much!
I came here for the first time just because I was curious about lightboard videos. I don't know who you are but I love your smile!
THAT'S GOOD

wow this is so useful
🥰
Excelent.
Thank you very much for telling us everything
Excellent. You gave solid examples, including the doctor's office.
That is 100% AI Blud 💀
This is a great video, thanks a lot!
Please what is the name of the app.
@sure_math_center I use iMovie to edit if that’s the app you are referring to.
Good explanation.

So no one has come to the conclusion that the definition of a reactangle wrong and may need updating. Its definition sound like a polygon or a quadrilateral..

Great, but in multiplicative reasoning why the endpoint which is 5m in tree A goes to the numerator and not the denominator?
Thank you for making this clearer.
Was having a discussion with someone about negating negatives in life is positive, but we couldn't agree. I said fighting is negative and injustice is negative but the fighting of injustice is positive because the result is justice. Destroying is negative and Disease is negative but the destroying of disease is positive because the result is health. He still kept insisting that the negating of negatives just increases negatives in life. I said that is because you are adding negative numbers, not multiplying them. What do you think is an easy way to explain this?
Tysm this helped a lot!
Finally someone who explains it clearly! Thank you!!!
Glad you found it helpful :)
Thank you! This has been hard as rocks for me to understand in the past. I am sooo glad I found this video. You laid it down simply and concisely with real-world examples that I was able to relate to and that made sense to my brain ... #Grateful
Glad it was helpful! Percentiles can be so tricky to think about :)
Thank you

Do you make light board videos for other people?
I have sometimes if a colleague needs help or there is a video that could be useful for other colleague’s students :).
:(
I'd like to know where I can get the the actual ingredients how much ingredients I use I need the measurements
Happy to see you back!🎉
Good to be back! :)
Very nice explanation! Never heard of a honours class, though. In what countries or systems do the exist?
Honors classes are like advanced classes. This is the name we give them in the United States. Hope that helps!
Omg this helped me understand what the heck my 10yo was trying to teach me bases and I had no idea what she was talking about. I'm still not sure I understand why we are teaching it to kids but now I can help her with her homework!!
So glad that was helpful! We teach kids about base 10 (not other bases though) because that it what we use in our society :). However, this was not always the case (if you look at the ancient Babylonian or Mayan societies). Hope that helps!
So helpfulllll
I'm so glad!
This is so helpful, thank you so much
This was incredibly well done. Thank you.
thankss i understood better
Is it possible to make a video covering how to calculate the difference between the two probabilities?
@stormisdumb I LOVE this idea! I have added it to my list :). Hoping to make videos in the next month or so!
What is the wo
Why?
❤❤well explained
You've made a grammatical error when describing 2 to the exponent 3 and the other powers. It is not 2 to the 'power of 3'. It's 2 cubed or 2 to the exponent 3. What's the power? The entire base and exponent is called a power.So 2 cubed is a power. Check it out.
Why do people get this wrong all the time? Look at it this way. In this case, it is literally the value of -6 squared, thus positive 36. Lots of people, including this video, get this wrong by saying -6 = -1*6, thus -1*6^2 is -36. (Even some calculators!) However, when you factor a square you must square ALL the factors, thus (-1*6)^2 = -1^2 * 6^2 = 1*36 = positive 36. You could also do this by -6 being equal to -1*2*3, and squaring all the factors, -1^2 * 2^2 * 3^2 = 1*4*9 = positive 36. You could also do this using the binomial square formula, (a+b)^2 = a^2 + 2ab + b^2. Pick any two numbers that equal -6. Lets say positive 10 and negative 16. 10+(-16) = -6. a = 10, b = -16 10^2 + 2(10)(-16) + (-16)^2 100+(-320)+256 -220+256 = positive 36. -6^2 is positive 36. This will be positive 36 for any two number you choose as long as it equals -6.
Hi J! You said "However, when you factor a square you must square ALL the factors, thus (-1*6)^2 = -1^2 * 6^2 = 1*36 = positive 36." Why did you put the ( ) around the -1*6? As soon as you put the ( ) around that expression, you are no longer simplifying -6^2. Instead, you are simplifying (-6)^2. If you were to list the same expression without ( ), it would look like this: -1 * 6 ^2. According to the order of operations, you would do exponents before multiplication. Therefore, your answer would be -1 * 36 or -36. I hope that helps clear up your confusion!
@@mathvideosthatmotivateI put them in parentheses because there is no other way to group a factor of a square. Let's look at it this way -6 = (-6), correct? Ok, square both sides. -6^2 = (-6)^2. This has to do with the reflexive property. The reflexive property states all values are equal to each other. a = a. It follows that all values are equal to each other in parentheses, a = (a). Therefore -6 = (-6) and -6^2 = (-6)^2. Since (-6)^2 is positive 36, through the transitive property -6^2 is also positive 36.
@@J-kd2qc I'm with you. As a computer programmer I tend to see calculations in algebraic terms: a^2, where the variable 'a' in this case is -6. a^2 = a * a -6 * -6 = 36
No because of order of operations where exponential operations should be done before subtraction operations that includes the negative in front of the 6 which means it's just 6 squared which is 36 then throw on the negative giving it -36
Horrible explanation reminds me of why l hated math so much as a kid.
Thanks!
The only thing more brilliant than the 6 lights is the whole light board idea and reversal in post. Very, very impressed!!!!!!
Thanks ma’am, I come here because percentiles confuse me sometimes!!
Well that's one huge mystery sorted! Thank you for this well done and crystal clear explanation of how these light board videos are made!
@dalematt you are so welcome! Glad this was helpful. :)
