DAY 295

Today’s Challenge

. . . is from Volume 1 of our MATHELONA pocket book. You have a limited amount of numbers to work with, so can you make all three lines work out arithmetically by replacing the 12 ◯’s with these numbers?

1      2      2      2      3      4      4      4      8      8      8      8

◯  +  ◯   =     5     =   ◯  –  ◯
◯  +  ◯   =    16    =   ◯  ×  ◯
◯  +  ◯   =     4     =   ◯  ÷  ◯
