DAY 76

Today’s Challenge

It is possible to use seven 4’s (4, 4, 4, 4, 4, 4 and 4) once each, together with the four operations + – × ÷ to make all the different target numbers from 1, 2 and 3.

For instance, to arrive at the number 1 you could do:

4 – [ (4÷4) + (4÷4) + (4÷4) ] = 1

Your task is just to make the next two target numbers, 2 and 3.  Can you make them?
