It could be: 9+91-1 = 10
99 + 9/9 = 100
22+2=24
4!+(4+4!)/4
You cannot perform any operation by giving any operator. The operation must be valid in the domain and range.For example, you often cannot perform the square rootoperation using the square root operator if your domain and range are integers. At the level of maths that I guess you are at (from this question), the square root of a negative number is not a operation that is defined.
(666 - 66)/6 = 600/6 = 100
I very much doubt if there are any two digits which can give 11934 using any standard mathematical operation.
(1+1+1)! = 3! = 3x2x1 = 6... :)
Watch closely . . . (7)2 = 49
No. You need at least four.
3.2 million of them, but you can write it without using any of them.
