36?

I've never actually learned this yet, but I think I understand pedmas

I didn't know quite what to do with the 12 from 9+3 though

so I just added it to 24 which is 48/2

It is 24. Your Calculator does not do Order of Operations.

Well, according to the order of operations (PEMDAS) the order you must evaluate expressions is in this order:
Parentheses
Exponents
Multiplication/Division (do whichever comes first)
Addition/Subtractions (do whichever comes first)

So, it would be as follows:
48÷2(9+3) - First you solve the parentheses
48÷2(12) - The parentheses simplifies to multiplication
48÷2*12 - Now you do the division first, since it came before the multiplication
24*12 - Just multiply together to get the answer
288

Now, the reason your calculator doesn't get it right is because you type it in all in at once, so it solves it as you type it in.

Understand?

Any questions?

Dude...it's 2.

I have done Algebra class and I'm halfway through Geometry.

We even do stuff like: 67x+56=546(6X4) (of course, that was Algebra). Now we just do lots with theorems like Hypotenuse-Leg and blah...

Every time I see one of these, I bang my head on the table a little more.


1) 48÷2(9+3)
Alright, so we're at the problem. Cool.

2) 48÷2(12)
PEMDAS (or BODMAS, if you're unique) says to do things inside parentheses (or brackets) first.

3) 48÷2(12)
There are no exponents, so we can skip that step.

3) 24(12)
This is where many screw up. The next part of PEMDAS (BODMAS) is MD (DM), which basically means, from LEFT to RIGHT, you multiply or divide. 48/2 is farther to the left than 2(12), so we do 48/2 FIRST. OKAY?

4) 288
We have your answer.

48÷2(9+3)

well

using PEMDAS you can simplify it to

48÷2*12

which we can simplify to

24*12

which equals 288

the mistake people are making is multiplying 2 by 12

which is incorrect, because it's the wrong order of operations

(I know this wasn't directed to me, but I now know how to do this thanks to you)

so for the parentheses you do them then add it in as multiplication?
