I'm trying to solve this puzzle:
Add operators to make the following equation correct: 4 4 4 4 = 2. Give 3 ways to do so. You are allowed to use brackets if necessary, but no rearranging of numbers or moving the equal sign. You may only use the following math operators: +, -, ×, ÷.
I can think of one or two, but this question wants three ways to do so. Any help in this problem is appreciated.
