Question

sayde borrowed $20 from her brother. When she got her allowance, she paid him back 20$. how much does sayde owe her brother now?

Answer 1

The easiest way for me to do this was subtract 20 from 0 and then add 20 to 0. Since the answer is 0, Sayde doesn't owe her brother anything (as far as we know).

Answer 2

Sayde doesn't owe her brother anything since she gave him the $20 dollars back.
