Q How can you make 5 twos equal five? Here's a solution that uses 5 twos — plus mathematical symbols that make the equation true.

2 × 2 × 2 + 2 ÷ 2 = 5

For each of the three rows below, insert the mathematical symbols (+, -, ÷, ×) that will make the equation correct for someone calculating from left to right.

a. 3 3 3 3 3 = 5
b. 4 4 4 4 4 = 5
c. 5 5 5 5 5 = 5


 
A a. 3 × 3 + 3 + 3 ÷ 3 = 5
b. 4 - 4 + 4 ÷ 4 + 4 = 5
c. 5 - 5 + 5 - 5 + 5 = 5
