I believe it’s a 100. Multiply first then Minus then plus.

OK, what I wanna know is who came up with this order of operation bullshit!

sorry I am a simpleton.

I asked and her response was ‘I don’t have time for those questions - google it yourself’

I guess that’s fair, my standard answer when someone asks me why something is the way it is. Because it is.

 

[Lavey5150]

Coke or Pepsi?
Duracell or Energizer?

 

[traquer]

-80. But really, who cares? In real life we'd know if the answer was ballpark correct or not based on the application lol. This is the kinda shit that drove me nuts in school. And the reason why I was so great at machining and trigonometry and terrible at equations. I could visualize it regardless of how complicated it was because the end result made sense.

 

[H20 Toie]

Way to confusing, everyone should know the only answer that matters is 42

I see it as

10-10 = 0
0x10 = 0
0+10 = 10

My education level...=)

 

[spectra3279]

Multiplication goes first.

So 10 × 10 =100
100 + 10 = 110
110 - 10 = 100

Where’s yellow boat ? Lol

 

[Willie B]

10-10x10+10=

10-10=0

0x10=10

10+10=20

So 20 ???…

 

[HBCraig]

Multiplication goes first.

So 10 × 10 =100
100 + 10 = 110
110 - 10 = 100

Multiplication first, then addition, the subtraction

110 - 10 = 100

You were on the right track at first.

start with 10 - 10 x 10 + 10
10 x 10 = 100 leaving
10 - 100 + 10
now addition at subtraction happen left to right. PEMDAS is a little confusing because it makes it sound like you do the addition next. But, addition and subtraction are basically on the same level and attacked left to right.
so, 10 - 100 = -90
-90 + 10 = -80
answer: -80

Order of operations

 

[OCMerrill]

Three human souls.

 

[QC22]

This one is still bugging me. So PEMDAS, SCHMEMDAS... Who gets to decide where the parentheses are placed?

I can write it (10-10) x (10+10) which is zero. Why are the parentheses around the multiplication portion automatic? Which "order of operation" demands that?

Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

The rules could have been decided differently as you point out and if everyone would do it the same, it would not matter. But if there are no standards for expressing mathematical solutions, then there are no standard set of solutions as the formula would not deliver consistent results.

Agreed, but I still don't understand who decides when and where the parentheses are placed. PEMDAS doesn't tell me that, right?

 

[Terminal Velocity]

@QC22 In 1912, First Year Algebra by Webster Wells and Walter W. Hart has: "Indicated operations are to be performed in the following order: first, all multiplications and divisions in their order from left to right; then all additions and subtractions from left to right."

 

[Flying_Lavey]

No. You need to go back to Algebra to figure that out. It all depends on the type of equation you are solving for. The basic principals are what PEMDAS is for. For example... calculating out hourly pay with OT would use PEMDAS if you wrote it all out. (figuring a $20 rate)

(40hrs x $20) + (5hrs x ($20x1.5)) = $XXX

Agreed, but I still don't understand who decides when and where the parentheses are placed. PEMDAS doesn't tell me that, right?

Roger, and it sort of explains my confusion. Those placing parentheses around the 10 x 10 are following that order. I think my confusion is that P is first in PEMDAS. So the P means IF there are parentheses, go there first. If there are no parentheses use the order of multiplication first, etc.

 

[530RL]

PEMDAS decides where the parenthesis goes when the original equation did not use parenthesis.

Parenthesis can be used by people to assure that the formula isn't confused when applying PEMDAS. If the original writer of the problem would have put parenthesis on as opposed to relying on the use of PEMDAS it would have been more clear, but defeated the point of making people re-learn PEMDAS.

In the original equation, there are no Parenthesis (P) and are no exponents (E). So next is Multiplication (M) or in this case the 10 x 10. Or one can simply re-write the equation with parenthesis using the rules of PEMDAS. 10-(10x10)+10

This is why teachers always harp on showing each step of work in school. When we were kids we would have to solve it as

10 - 10 x 10 + 10
10 - (10 x 10) +10
10 - 100 + 10
-90 + 10
-80

Missing any step meant it was wrong. But they were priests and priests have a lot of authority issues......

correct, if there were already parenthesis around the 10-10 then you'd start there. Since none, you move to the next order of Multiplication or Division in a left to right order.

 

[84miller]

Zero (0)
10-10 = 0
0 times X any number is 0
So it does not matter what is on the other side of the equation.

Wrong. See above referring to order of operations.
