## MSH! Classes - Your Computer's Calculator

 Your Computer's Calculator This is not a chain-logic calculator and not a scientific calculator. It has features of each of these.     This page serves as an itroduction to the machine and to mathematical ideas listed below.     A reference table and examples are also provided. NOTES: No points have been marked on these pages for BREAKs. Decide for yourself when to break. On these pages the "Calculator Button" links you to the picture above so that you may see the placement of the calculator keys as you review their use. Keep both notes open and your calculator open.
