Computer Math

Computer codes, internet searches, ISBN, and credit card numbers all involve mathematics. This unit will introduce some of the mathematical concepts behind these topics. Only the solution guides have been uploaded to this page so you can check your work. The unit gets adjusted some from year to year based on time remaining in the school year. The lessons are numbered as if we have time to complete the entire unit.
