6/2(1+2) = ?

That's a very good post.

 

i guess it is when you decide you can move the parenthesis around...

 

X2....obviously potato.

 

9 Fo Sho

I thought it was 1 at first glance.

 

that equals 9....lol

 

So it seems we can all agree Hitler was right all along?

sorry this video just makes me laugh, I don't know why.

 

6/2(1+2)= 9

 

I am too and I just asked three other engineers and we all answered 9.

 

*Fist Bump*

 

6/2(1+2)

6/2(3)

3(3)

9


an extra set of brackets, or interpreting " / " as over instead of divided by, would (obviously) change the result

6/(2(1+2))

6/(2(3))

6/(6)

1

 

screw you guys, I'm going home. I am severley dislexic at math. My brain hurts now.
I guess it how you read it?

 

x2.


6(1+2)/2
6(3)/2
18/2
9

 

9 because you must do operations from left to right after making the parathensis

 

The answer is 9

 

At first I thought it was 9, 6 div 2, times 1 plus 2 equals 9. Then I thought no, mult before div, so 6, div by 2 times 3 equals 6, so 6 div 6 equals 1. I then read that in order of operations mult and div get read left to right and are in the same heirarchy, so my original answer of 9 would be correct.

I say nine, and that no one is stupid for either answer, i was taught PPMDAS please please my dear aunt sue for powers parentheses multiplication division addition subtraction, not only is that order wrong, multiplication and division are equalites as are addition and subtraction and should be read from left to right. Well thanks TW, you made me relearn something.

Gorsh.

 

Answer could be argued either way. But the expression lends itself more to a fraction than a straight equation: 6 over 2 times 3 = 1.

 

This is the most active forum I've ever been on

 

Algebraic expressions are worked from left to right. That's the rule. Live with it. 9
