How do you make 26 using 1,2,3,4 only once

Hello,

It is easy, you can descompose the number to do it easier:

26 | 2

13 | 13

1

26 = 2 * 13

We have 2, so, we have to get 13 with 1, 3 and 4

3*4 = 12

12+1 = 13

We got it, so the answer is:

2*[ (3*4) + 1]

Now, the excersice doesn't say that we can't put it together, so I think this can be another answer:

24+3-1=26

2x (4x3+1) Is the answer
