Question 227211: I'm in the 6th grade.My question is:Integer rules when the signs are different you are supposed to subtract,are they talking about the signs in paranthes
EX is (+9)+(-8)= the two signs are different so do i just subtract both now,because the signs in parantheses are different

You can put this solution on YOUR website!
(+9) + (-8) is the same as (+9) - (+8).

You would subtract.

the answer is 9 - 8 = 1

It's the operator combined with the sign that determines what you do.

The sign is within the parentheses. It tells you whether the number is negative or positive.

the operator is outside the parentheses. It tells you whether you will be adding or subtracting.

adding a negative number is the same as subtracting a positive number.

+ (-9) is the same as - (+9)

when you combine the operator with the sign, the rules are:

++ means add
+- means subtract
-+ means subtract
-- means add

the first sign is the operator.

the second sign is the sign of the operand (the number you are working on).
