1 * (2+3) * 4/5

Step-by-step explanation:

There are many ways to do this. You can take advantage of identity element properties (as above, where we multiply by 1 and by a ratio whose value is 1), and you can take advantage of multiples and factors.

4 = 8/2 = (5+3) / (4-1·2)

4 = 5-1 = 5 + (4-3-2) ·1

4 = 4+0 = 4 + (5·1 - 2 - 3)
