Vibecoding 2: a program is steps in order

The same two steps, add 3 and double, in two orders give two answers, and a loop repeats one step. Lesson 2 of the vibecoding course.

Two orders A loop

A loop: add 3, four times

start: 2
after 1 step: 5
after 2 steps: 8
after 3 steps: 11
after 4 steps: 14

Two orders A loop

Two steps, two orders, start at 2
Order	Result
add 3, then double	10
double, then add 3	7

Swap two steps and the answer changes; the loop is one step written once.
