Sir may I just point out the expression that you did...9-12÷3×2=1, you got 7 which is an error. If you punch this expression into a calculator you will not get 7. The reason you got 7 is because you did...3×2 first. Both multiplication and Division are a order of priority. So if Division comes before Multiplication In a given expression (like in this case), moving from left to right. Division SHOULD BE DONE before Multiplication. So that's why when you punch this expression into a Calculator or Ai program you will Not get 7 but 1. Remember the expression is being solve from left to right. So if Division comes before Multiplication it is to be done first. Both are a order of priority. It is just a matter of which one comes before the other from left to right.

Please control your mouth noises

Where did you get your 10 from

thank you so much it was helpful

3:14 even numbers, which when divided by e ........ was this planned to happen at pi minutes? .

Sorry to say that it is a very poor presentation 😢

This was great but pemdas is parentheses, exponents im pretty sure

Very informative, but the sound of you sucking on a candy was really annoying.

In PEMDAS, P stands for parenthesis and E stands for Exponents.

Part 2 please

Multiplication always coming first doesn't make sense to me because 32 ÷ 2 × 4 - 5 can also be rewritten as 32 × 1/2 × 4 - 5. In which case, 16 × 4 - 5 gives 64 - 5; whereas 32 ÷ 2 × 4 - 5, with your explanation gives 32 ÷ 8 - 5, which seems to be completely wrong to me. Can I have an explanation as to why it isn't just multiplication/division from left to right? Cuz, again, division is just multiplying by the inverse

ngl ur handwriting is beautiful

I thought that when we have absolute value, the results will be always positive. So if we put -1 inside the absolute value, the results will be 1. So i got confuse in the question no. 4, i thought it was injective haha. Please correct me if i'm wrong😊

This video deserves millions of views 🔥🤍🤍🤍 , thank you so much

Were you eating candy while speaking? The sound is annoying to be honest.

Who has exam tmr

Thank you🥰🤗

this really helped me a lot for my exam which is tmr , loved your explanation

love you boss

Proving that a linear transformation is bijective seens so much easier than proving that a normal function like y=x+3 is bijective for some reason

Amazing video!!

Great video🎉🎉

There is also bodmas too the caribbean mostly use this

Perfect👏🏾👏🏾

didn't get anything

ITS A TRAPEZIUM!!!!

exellent video, very transparent

Is it ok if we round off?

I am surprised at the way you handle the minus sign. The minus sign is used to indicate two different things in mathematics. It can be used to represent a negative number which tells us how far to the left of zero the number is. Secondly, it can be used to indicate the binary operation of subtraction which is defined as the addition of opposed of the number being subtracted. The minus sign has no mathematical meaning. To solve expressions, first change all operations of subtraction to addition and then apply the rules for adding positive and negative numbers which can be easily explained using the number line. Cheers.

Thank you got a better understanding of this concept 👍

You teach so well where is part 2

Awesome and easy

Is it true that negative numbers can be even? Odd? I thought only positive ones could be even or odd

Thanks this by far the clearest video , def subscribing

great explanation.

I love this one. The foundation of ontology, knowledge representation, logic, and computational science.

Good stuff. Where is part 2 ?

Intermediary section, example 3 is incorrect.

ive being trying to learn this in class for two year, but ive just learn it in 8 min

The perfect way to start limits

this video is so good

20:53 where did you get the "divided by a-5" from? x (5 - a) = -1 - 2 a, so x = (-1 - 2a) / (5-a)

Big up

Great examples and excellent explanation. Thanks!

This video is on fire❤‍🔥❤‍🔥❤‍🔥

I learnt alot 💯

4:50 WAS EXPLAINED SO WELL!

Powerful part of foundational math, thanks for the video.

I love the consistent notation and build up

Up 💖🙌
