So, you know the values of a, b, and c. You have an expression with the variables a, b, and c.
Because you know what each variable equals, you can substitute each number for its respective variable.
The expression is:
a - b + c =
And, a = -2
(-2) - b + c =
You can then substitute the other variables for their numbers and simplify the expression.
If a= -2, b= -5 and c= -6 than
a - b + c =
I don't know how to complete this problem?

you are right, I have the variables but I don't know how to simply the expression with all the negatives and positives. This is just an example of what I'm working on:
(-2) - -5 + -6.
If you can explain that part, I'm sure I can apply it to the rest of my homework.
(-2) - -5 + -6.
If you can explain that part, I'm sure I can apply it to the rest of my homework.
-2 + 5 - 6
