Try some examples.
+ 8 - (-8)
Remember when you subtract, you add the opposite in algebra
+8 + (+8) = 16
+ 10 - (-4) = "
Look for a pattern.

B always positive
for example, this would be positive number - negative number = positive number + - - positive number = positive number
3 (positive number ) - (-14) (negative number) = 3 --14 = 3+14 = 17. btw it cant be 0 because the first number is positive
