How many different combinations of four 4s make 2?

Answer 1

4/4 + 4/4 = 2 (one)

4 - (4+4)/4 = 2 (two)

(4*4)/(4+4) = 2 (three)

4*(4/(4+4)) = 2 (four)

((4+4)/4) mod 4 = 2 (five)

4 + √4 - √4 - √4 = 2 (six)

((√4)/(√4)) + ((√4)/(√4)) = 2 (seven)

4 + 4 - 4 - √4 = 2 (eight)

(√4)^4 / (4+4) = 2 (nine)

(√(4*4)) / (4+4) = 2 (ten)
