DAY 182

Today’s Challenge

. . . is my fun & challenging number puzzle, MATHELONA.

Can you replace the 12 ◯’s below with 0, 1, 1, 2, 3, 4, 5, 5, 6, 7, 9 and 9 so that all three lines work out arithmetically?

◯  +  ◯    =     4     =   ◯  –  ◯
◯  +  ◯    =    18    =   ◯  ×  ◯
◯  +  ◯    =     7     =   ◯  ÷  ◯
