If I have 20 apples and I eat 20, and a friend gives me 20 more, and I eat those 20 again, how many apples do I have in total?

0

Step-by-step explanation:

If you have 20 apples and you eat 20, and a friend gives you 20 more, and you eat those 20 again, 20-20=0+20=20-20+0

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.
