Fit the discs, just need to add and subtract tto make each answer

i got 86 for this

hope this !

if you need an explanation just ask

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
