What functions, decomposition, and debugging means

A function is a named set of instructions. Decomposition means splitting a program into small jobs so each job is easier to test and explain. In a program, the computer follows each instruction exactly. Read the code slowly, name what each line does, then run one small change so the idea becomes visible.
