Tutorial-02 for CoCoA-5

CoCoA-5 includes its own "imperative" programming language. Values you plan to use in future computations need to be "stored" in variables; the act of storing a value in a variable is also called "assignment". CoCoA-5 uses the "colon-equals" operator to indicate assignment.

A variable name must start with a letter, and may contain letters, digits, and the underscore character. We recommend using names which are mnemonic (but hopefully not too long).

The most basic types in CoCoA-5 are integers, rationals and strings. A number written in "decimal notation" is automatically converted to a rational number.
