DAY 188

Today’s Challenge

Try the following number challenge similar to the ones that can be found in my MATHELONA pocket book of challenges. For details, click this MATHELONA link.

Your task is to make all four lines below work out arithmetically by replacing the 16 ◯’s with the following list of 16 digits. Can you do it?

0    0    1    1    2    2    4    4    5    5    6    6    7    7    8    9

◯  +  ◯   =    15    =   ◯  +  ◯
◯  +  ◯   =     2     =   ◯  –  ◯
◯  +  ◯   =     8     =   ◯  ×  ◯
◯  +  ◯   =     1     =   ◯  ÷  ◯
