Why do you speak of left to right order? Multiplication and addition have both the commutativity property : a*b = b*a and a+b = b+a, and if we write the division '/x' as a multiplication '*(1/x)', and the substraction '-x' as an addition '+(-x)' , there is no need for left to right order!!! We can change the order, that does not change the final value 40/4*5 = 40*5/4 = 200/5 = 50 or 40/4*5 = 4*10/4*5 = 4/4*10*5 = 1*50 = 50 the only thing to take care of is to move the sign with the associated value (and if a denominator is present, move the full denominator with the division sign) So if I were to solve it rigth to left, I'll write it : 40/4*5 = 40*1.25 = 50 (1/4*5 = 5/4 = 1.25) The same with 9/3*2/6 and 8-5+7-1 We can change the order and make some regroupement : 9/3*2/6 = 9*2/(3*6) = 18/18 = 1 8 - 5 + 7 - 1 = 8 + 7 - 5 - 1 = 8 + 7 - (5 + 1) = 15 - 6 = 9 It's because of such teaching that is called 'modern order of operation' that when they'll later see an expression like a/bc, for them the 'implicit multiplication' as 'unseparated letters' notation will be lost, and they'll interpret it (a/b)*c instead of a/(b*c) ... for them the left to right order should take precedence other any other rules... But the good answer for 'a/bc' is 'rewrite that expression because it is ambiguous', (remove the implicit multiplication/add the invisible parentheses to be able to use the 'classical' order of operation) is it a/b*c or a/(b*c) the same with 4 __ 2 __ 2 In mathematic, such expression is wrong, nobody can say what is the answer. Is the main division symbol between 4 and 2 or between the two 2? Is it 4/(2/2) or (4/2)/2 ? No way to know !!! and if somebody give an answer it can only be wrong !!! But if someone rewrite it 4/2/2 and then use BOSMAS/PEMDAS, he'll say that the answer is (4/2)/2 = 2/2 = 1, but to give that answer for that problem is very wrong !!! So when you do such course presentation, do not forget to add that such rules can only apply to basic math expression and should not be used anymore when 'advanced' math notion are present...

Adding two numbers is an answer. Looking at the plus in the front of a number will tell that is positive. Because they are positive, writing a plus in the front may be too tricky in a car, but it could be a lot faster to write it at home, At least the sum is really positive. If a number has no sign, at least no sign, it’s positive.

Well ! That's a really good video indeed! I learned the same way in Hungary but here in UK my grandson learned a different way and when I asked their teacher he said my way is an old method and they learn a new method now, but in that case they got a different sum at the end. So in the old times how they built a bridge or houses? - if they were "wrong" ? Bidmas bodmas xmas... I saw many videos and You are the best!

He forgot parentheses inside parentheses, ;) You start with the inner most parentheses first and work your way out in those cases.

I think my math teacher's stressed because of paperworks... she said that: Multiplication first before division Addition first before subtraction.. I've been doing what's said in this video ever since I was in 3rd Grade... but I've been getting wrong checkmarks when I do what's said in this video... I hope so that she won't get stressed anymore and know that MD and AS is left to right XD ... I hope that you get better, my math teacher! ☺️
