Today’s Challenge
This challenge has been taken from our brand-new series of MATHELONA number puzzle pocket books.
Can you complete this task so all three lines work out arithmetically when inserting the digits 0, 0, 1, 1, 1, 2, 3, 4, 5, 6, 7 and 8 into the 12 gaps below?
◯ + ◯ = 6 = ◯ – ◯
◯ + ◯ = 15 = ◯ × ◯
◯ + ◯ = 1 = ◯ ÷ ◯
