The absolute value of a number is the number of units it is from zero on the number line.
For example: -9 and 9 are both 9 units away from zero.
Calculate each term of the question.
Absolute value of -8 is 8.
Absolute value of -3 is 3.
Absolute value of 7 is 7.
now we have 8 + 3 - 7
Final answer is 4.
