(4*4)-(4/4)
Only if you subtract three.
4! - 44/4 = 24 - 11 = 13
4 - (4+4) x 4
4*4 - 4/4 = 16 - 1 = 15.
4(4 + 4/4) = 4(4 + 1) = 20
4 + 4 + (4/4).
4/4 x 4 =16/4 = simplest form = 4
11 = 4/.4 + 4/4
44 minus the square root of 4 divided by point 4
It could be: 4+40+40 = 6
One possible solution is: 4.4 + 4 / .4 = 21
