13. That's what I think too.

I was taught MDAS for order of operations.
5 + (1x10) =15

If it is something else, I'd like an explanation.
Maybe the answer is "heart attack."

18. I Get 25 Cents

3 cokes are 30, so 10 cents a piece.
A coke & 2 burgers is 20. 20 minus 10 is 10, 10 divided by 2 burgers is 5 cents a piece.
Burger & 2 chips are 9, so chips are 2 cents a piece
A burgers plus (chips TIMES a coke) is 5 + (2 ◊ 10) or 5 +20 = 25.

22. I see "Burger + 4 chips equals 9"

The burger is combined with 2 pairs of chips.

26. I almost did the same thing.

I figured the answer as 15. I'm curious as to why that's wrong.

27. Order Of Operations

Multiplication/Division always comes before addition/subtraction, unless the subordinate operation is in parentheses. The mnemonic is PEMDAS. (Parentheses, Exponents, Multiplication/Division, Addition/Substration.)
So, it's 5 plus 1 times 10.
I got it wrong because I didn't notice it was 2 pairs of chips, not 2 chips.

29. So under Order of Operations,

You multiply 1 times 10, which equals 10.
You then add 5. So total is 15. Right?

30. That's What I Get

So did Si8. But, Si8 was told that's wrong. We don't get why.
But yes, based on PEMDAS, it would be 15, assuming we're not missing something like I did with the pairs of chips.

You and whoever said




15 are right !!?!!!



I screwed up majorly and believed someone . Sorry!!!!


BTW, you'd never try and add the hamburger 5 to the chips 1, correct? Which would equal 16. (10x1) + 5+1

34. Correct

The chips were used up in multiplying it by the Coke.
If we added them to the 5, we'd be using it twice.

41. As You Probably Know...

...my wintertime occupier of time is subbing math & science.
6th and/or 7th grade go through order of operations.
So, I've been specifically trying to get it understood in a way 11 - 13 year old kids would get.
Not dumbing down, but definitely simplifying.

And it's not 2 but one. Look at pic again.
