DAY 264:

Today’s Challenge

Your task is to make the four lines below work out arithmetically. Simply replace the ◯’s with digits from 0 to 9, but each digit can only be inserted a maximum of twice.

◯  +  ◯   =    12    =   ◯  +  ◯
◯  +  ◯   =     1     =   ◯  –  ◯
◯  +  ◯   =     5     =   ◯  ×  ◯
◯  +  ◯   =     2     =   ◯  ÷  ◯
