Evaluate the following for the given values:
a-b, for a = 5 and b = -6

+11

Step-by-step explanation: In this problem were going to

evaluate a - b knowing that a = 5 and b = -6.

So the first thing we want to do is substitute

these numbers into our problem.

It's a good idea to get into the habit of using parentheses

when substituting numbers in for variables.

So we have (5) - (-6).

When you see a minus a negative in a problem,

you can change it to plus a positive.

So (5) - (-6) can be thought of as 5 + (+6).

So just add 5 + 6 to give you +11.

So the answer is +11.

11

Step-by-step explanation:

We are given the expression:

a-b

and these variables: a= 5 and b= -6.

Therefore, we can substitute 5 in for a and -6 in for b. Don't forget to use parentheses.

(5)-(-6)

When a negative number is subtracted from another number, or there are 2 adjacent negative signs, they can be turned into a plus sign.

5+6

Add 5 and 6
