Answer 1

Range is defined as the difference between the highest and the lowest. Difference means subtraction.
119-(-54)= ______________
119+54 = _________

If you have trouble with subtracting integers think of a thermometer. 119 is 119 degrees above zero. -54 is 54 degrees below zero. To find the difference between the two marks on a thermometer you would add 119 and 54.
