Can you use 3 equal digits to express the number 24? The mathematical signs you can use are addition, subtraction, multiplication, division, square root (√ ), decimal points, and the factorial sign (!). As a matter of fact, you can use any mathematical sign you can think of.
Two easy and obvious examples are: 8 + 8 + 8 = 24 and 22 + 2 = 24. Can you figure out other ways using other digits?
