4 + 1 - 2 = 3
48
106------------------------------------------------------------------------------------------------From Rafaelrz.You can make, 4P3 = 4!/(4-3)! = 24, different 3 digit numbers using 1, 2, 3 and 4.
5+4-3+2
256!
5! / 4 - 2 * 3
(4 + 3) * (2 - 1)
If the digits are repeatable, the answer is 4*4*4*4. If the numbers cannot be repeated, then it is 4*3*2*1.
25 + 3 + 4 = 39
4+2=6 6-3=3 3-1 2
(4! + 2 + 3) x 1 [For those who do not know, 4! = 10]
It is a pattern. Go up two numbers, go down two numbers.
