print("""original order: +*-/s this generates b-1
interesting: -/+*s this makes (b-1)*b

To run a test use run_test with parameters specified in the function like so
run_test("+*-/s",2)
The order syntax is each operation with s being subtracting the original number.
You can alos do something like so
run_test("+*-/s",2,-100,100,10)
This will go from -10 to 10 with a step of 0.1. see comments in code for more info""")
