Problem: THE FOUR FOURS

Using nothing but the figure 4 four times, no more or no

less, derive all the numbers from 0 to 36.

Here are some examples:

15 = 4 x 4 – 4/4

19 = 4! – 4 – 4/4

23 = 4(4!) – 4

Note: 4! means “factorial 4” which is 4 x 3 x 2 x 1.

Ensure your solution shows full working (if necessary)

and has your name clearly on it.
