The answer is 7.

Explanation:

For any number c, the absolute value of c (denoted as abs c) is simply the distance that number is from 0. The absolute value of a positive number is simply the number itself. If the number is negative, its absolute value is the number without the negative sign.

Thus, to evaluate a+b+abs c when a=0, b=3, and c="-4", we just plug the numbers in where the matching letters are, and we get

color(white)= a + b + abs c
=0 + 3 + abs "-4"
=0 + 3 + 4
=7

So our answer is 7.
