Nothing on this test is intended to be tricky.  * means multiply.

If you do not see an exponent in problems #5,  11, 21, 24, 25, 26  then stop and email me about this.  Please show a little work on each problem where possible.

DO NOT USE A CALCULATOR.   I need to understand what you know when you are working without any type of math help. 
Send your answers/work by email, please.
I will reply within one day. Please let me know with a polite note if I do not.

Complete test  within 1 hour, but do finish it.   Tell me the time that you took.
