Order of operation says ( exponents first  then multiply/diide then add/subtract_ )  so first you do the multiplication 5x0=0

5+5+5-5+5+5-5+0

since now its all add/subtract the order doesnt matter according to order of operations you add/subtract from left to right

the answer is 15
answered Nov 9, 2011 by Killer Al (380 points)
it would be 15 because you have to multiply the last 5 by 0 before you do anything (:

15 is the answer.

5 + 5 + 5 - 5 + 5 + 5 - 5 + 5 x 0 = ZERO

Multiply any number by zero and you have ZERO!

Original Problem:
5 + 5 + 5 - 5 + 5 + 5 - 5 + 5 x 0 = ___

Use PEDMAS
()
^
% or *
+ or -

First multiplication.
5 + 5 + 5 - 5 + 5 + 5 - 5 + 5 x 0 = ___

Then addition/subtraction. 
(Done from left to right, not "all addition first, then all subtraction".)

5 + 5 + 5 - 5 + 5 + 5 - 5 + 0 =___
10 + 5 - 5 + 5 + 5 - 5 + 0 =___ 
15 - 5 + 5 + 5 - 5 + 0 =__
10 + 5 + 5 - 5 + 0 =__
15 + 5 - 5 + 0 =__
20 - 5 + 0 =__
15 + 0 = ___

Your answer:
15

Multiply 5x0 first per order of operations of PMDAS

then complete the math problem
answered Jul 29, 2012 by anonymous
I was taught the order of operations is ASMD(Addition, Subtraction, Multiplication, then Division in that order.  Exponents & Parens are done first.. Been programming for 25+ years and havent been wrong yet..

Now you guys wanna change my order of precedence?
answered Aug 1, 2012 by anonymous
YES! I want to change your order of precedence, because it is WRONG!Q!!!!!
Always do multiplication and division BEFORE addition and subtraction.
You may have been programming for years, but you have always been wrong.
5+5+5=15

15-5=10

10+5+5=20

20-5=15

5 times 0=0

the result is 15

by using PMDAS, the answer is 15?
answered Aug 2, 2012 by anonymous
well multiplication gets done first 5 x0 = 0

 

The rest is childs play (+ and -) have same order of ops ...

 

So you're left with : 5 + 5 + 5 - 5 + 5 + 5 - 5

Which is : 15

answer is 0 ... anything times 0 equils 0
answered Sep 13, 2012 by anonymous

5 + 5 + 5 - 5 + 5 + 5 - 5 + 5 x 0 = 0

answered Nov 1, 2012 by anonymous
if any number is multiplied by 0,the answer will be 0.guranteed
answered Dec 17, 2012 by anonymous
Guaranteed, yes, but there is only ONE factor that is multiplied by zero, the last one. You still have a string of addition and subtraction to do AFTER that single multiplication.
The answer is 15, guaranteed.
