DAY 283

Today’s Challenge

. . . is MATHELONA with a difference, not an addition in sight!

But can you still make all four lines work out arithmetically by replacing the 16 ◯’s with digits from 0 to 9?  Remember, each digit can only be inserted a maximum of twice:

◯  –  ◯   =    6    =   ◯  ×  ◯
◯  –  ◯   =    2    =   ◯  ÷  ◯
◯  –  ◯   =    8    =   ◯  ×  ◯
◯  –  ◯   =    1    =   ◯  ÷  ◯

Full details of our pocket book can be found by clicking MATHELONA.
