Can you make this equation true?

Logic Level 2

9     9     9     9  =  100 \LARGE 9 \ \ \ \ \ 9 \ \ \ \ \ 9 \ \ \ \ \ 9 \ \ = \ \ 100

What is the fewest number of operators (+,,×,÷)(+, -, \times, \div) needed on the left hand side of the equation to make the statement true?

Details and Assumptions:

  • For example, if the equation 9+9+9÷9=100 9 + 9 + 9 \div{9}= 100 is true, then you have used 3 operators: one division and two additions.

  • You are allowed to concatenate the digits, but it does not count as an operation. (That is, you can treat 9 9 as 99.)
