The issue here is that people think parenthesis and multiplication are interchangeable. While they function the same way, in the context of Order of Operations, they are not interchangeable as parenthesis always comes first. Anything next to the parenthesis ( in this case, 2) gets distributed into the parenthesis via multiplication before you can proceed down the PEMDAS order.

This is where people falter. They think division comes first because it appears before the multiplication. But in this case, the multiplication is actually a parenthesis which, according to PEMDAS, comes first. Not only do you solve for what's inside the parenthesis, but anything outside the parenthesis ( 2(10) ) also counts as a parenthesis operation. Hence it becomes 20

i agree

>>684872944
First, this problem is written extremely poorly. It should be written like this 20/(2(5+5)). If you think about it, the 20 is in the numerator and the 2(5+5) is in the denominator or else the problem would be written as (20/2)(5+5), which it is not. Therefore the parentheses I added makes sense.

So doing the math is now easy, just PEMDAS it out.
=20/(2(5+5))
=20/(2(10))
=20/(20)
=1

OR

=20/(2(5+5))
=20/(10+10)
=20/(20)
=1

Same thing. The answer is 1.

The multiplication mentioned here is not included in the parenthesis priority, that only applies to anything found INSIDE the parenthesis.

Therefore, proper notation for this problem is as such:

20 / 2 * (5 + 5)

Using distribution properly it's

20/2(10)
10(10)=100

You're approaching the equation by looking at the parentheses first, which is a bad habit that I blame schools for. Distribution is a neat trick, but PEMDAS means you have to solve the equation from left to right, starting with 20/2.

yes the calculator is right strictly. but when writing it out 2a and 2*a are not always the same thing. omitting the * generally groups the terms together, so 2a=(2*a). The real fault is writing the expression in a way that can be interperetted in more than one way

That is making the division into a fraction. If it was a fraction, the answer would be 100. But it's represented as division, which is two separate numbers. Thus making it 1. The way it's represented makes a difference. Yes, fractions are division, but when it comes to calculators, they're picky like that. 20÷2(5+5) is one, but 20/2(5+5) is 100.

PEMDAS is not the law, it is just a helpful set of guidelines for solving most arithmetic problems. So you can't cite it as a reason for anything.

This post, even aside from the stupidity that went on with the second line there, is blatant bait because of this usage of the division symbol. It could be interpreted as:

>20 / (2 * (5 + 5)) = 1
or
>(20 / 2) * (5 + 5) = 100

and neither option would be incorrect. The usage of ÷ as an operation is inherently vague. We cannot decide on the answer to this question because the question is made poorly.

So stop making threads like this you shits.

Would these two items not be mathematically equivalent. Then solve. At least this is what I remember from basic Algebra.

The problem is that you *do* make that assumption. It's the assumption that I would make myself, but there is no way to know what the original intent was because of the stupidly vague notation. 1 and 100 are equally correct, although 1 is a bit more sensible when you understand math better.

No, the priority with parethesis is that you solve what's inside the parethesis first.
Something like 2(10) is exactly the same as 2*10
So the equation is 20/2(5+5)
So first the parethesis (5+5)=(10)
Then mul/div with the same priotity
20/2(10) or 20/2*10
10(10)
100
