A simple test follows:

Hello, world!

Start with the increment operator:

a1 = 0

a1 = 1

a1 = 2

Now the decrement operator:

a2 = 5

a2 = 4

a2 = 3

a2 = 2

a2 = 1

a2 = 0

a2 = -1

Now the add operator:

op1 = 5, op2 = 3, op3 = 8

op3 = 11

And the subtract operator:

op1 = 5, op2 = 3, op3 = 2

op3 = -1
