EZ PCalc is a simple programmable calculator. Click here for help and a complete explanation, but a quick introduction follows.

EZ PCalc is meant to be a handy tool for performing most types of common scientific mathematics. At this site it is usually found on pages that include multiple choice questions that involve calculations. With EZ PCalc you can declare variables and initialize their values. Then you can use these variables (along with numbers, math operators, and functions) within a stack of expressions that are evaluated one after another, top to bottom, until a final result is reached and presented.

- Type a math expression (like
) into the blue input box*5 + 2* - Click
, the result (*'Calculate'*) is presented in a green box.*7* - Click
to expose*'More'*inputs (*variable name*) and their corresponding*yellow*inputs (*value expression*).*blue* - Once a
(*variable*) is declared and set to a*yellow*(*value*), it can be used in any following*blue*(*expression*).*blue*

So, a yellow box holds the name of a variable (like * a*
