Answer 5

Welcome man, just remember when you have a - in front of parentheses like this...

-(abunchofnumbershere)

its like

-1*abunchofnumbershere=-abunchofnumbershere

Answer 6

how bout on like this , 25/14 + (-13\14)=

Answer 7

When you multiply a positive by a negative you get a negative right?

Or when dealing with the + in front of the (-13/14) to alleviate confusion they have to add in the parentheses or it would look like this...

25/14+-13/14...that can be confusing. Think of the parentheses as a shields up, protecting the contents of the parentheses from that pesky + sign.

Answer 8

well the problem is actually -25/14 +(-13\14)= ......the answer i got was -2 5/7 simplied , but not sure if that is correct?

Answer 9

The answer is -19/7

7 will go into 19 twice with 5 remaining

-2 5/7 is right
