Wrong Multiplication

This game is based on one of my favourite show's minigames. A variety show called 'Running Man'. They play this game sometimes in between their main games for some extra rewards.

The rule of the game is simple: When given an equation, input an answer! What kind of answer? The answer needs to have the correct digit in the tens place and the wrong digit in the units place.
