Put four 4’s on a sheet of paper.

Then, by placing one equation symbol (x – + ÷) between each of the fours, get a total of all numbers 0 through 9.

Don’t forget your parenthesis!

Extra Challenge

Make all numbers 10-20

To do so, you will need to use more than just the four symbols listed above.

4 + 4 – 4 – 4 = 0

(4 + 4 – 4) ÷ 4 = 1

(4 ÷ 4) + (4 ÷ 4) = 2

(4 + 4 + 4) ÷ 4 = 3

(4 – 4) x 4 + 4 = 4

(4 x 4 + 4) ÷ 4 = 5

(4 + 4) ÷ 4 + 4 = 6

(4 + 4) – (4 ÷ 4) = 7

(4 + 4) + (4 – 4) = 8

(4 ÷ 4) + 4 + 4 = 9

√4 + √4 + √4 + 4 = 10
