to find and fix errors in one’s code

definitions area

the left-most text box in the Editor where definitions for values and functions are written

design recipe

a sequence of steps that helps people document, test, and write functions

error message

information from the computer about errors in code


shows the use of a function on specific inputs and the computation the function should perform on those inputs


a computation written in the rules of some language (such as arithmetic, code, or a Circle of Evaluation)

a type of data for pictures

interactions area

the right-most text box in the Editor, where expressions are entered to evaluate

a data type representing a real number

pie chart

a display that uses areas of a circular pie’s slices to show percentages in each category

programming language

a set of rules for writing code that a computer can evaluate

purpose statement

a brief description of what a function does
