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#.
