Directions: type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar( the expression 113.47 - (43.72 - 26.9) represents a.. the expression 113.47 - (26.9 - 43.72) represents b.. the numerical value of a - b is .. the numerical value of b - a is .

We are given with two expressions: (A) is 113.47 - (43.72 - 26.9) and (B) is 113.47 - (26.9 - 43.72). The numerical value of A-B is 113.47 - (43.72 - 26.9)- [113.47 - (26.9 - 43.72)] equal to -87.44 + 53.8 or -33.64. When B- A is to be computed, this is equal to the negative of A-B or equal to 33.64. We just have to be careful with the signs.

If you make you answer for clear i can answer it : )
