# Subtraction and Division Look Similar

**Number Theory**Level 1

\[\Large \color{red}{A} - \color{blue}{B} = \color{red}{A} \div \color{blue}{B}\]

If whole numbers \(\color{red}{A}\) and \(\color{blue}{B}\) satisfy this equation, then what is \(\color{red}{A} + \color{blue}{B}?\)

**Bonus:** Can you explain why there is only one solution?
