Question

Write an expression that has a value of 100 and follows these restrictions.

1. Uses each of the four operations at most once 2. Uses no parentheses

3.. Uses only the digit 3

Answer 1

3(33) + 3/3 = 100

Answer 2

3 * 33 + 3/3 = 100

With no parentheses, we follow the basic hierarchy where multiply and divide come first.

Thus:

3 * 33 + 3/3 = 99 + 1 = 100
