How do you get 37 by using four fours?

Negative Minus Negative = Positive so -4-4= 4 ericrain- No... We have to use 4 fours not 2 fours, so 4+4(4-4)

(4+4) x 4 + 4 + (4/4)

4+4+4=12 12/4=3

4 times 4 minus 4 minus square root of 4.

4+4+4-sqrt(4)4 / .4 + 4 - 44 / .4 x 4 - 44 + sqrt(4) + sqrt(4) + sqrt(4)44/4.4(44 - 4) / 4
