The numbers 0, 1, 2, 3, 4 displayed in a horizontal row at y = 50 on a yellow canvas

The numbers 1, 2, 3, 4, 5 displayed diagonally on a yellow canvas

The numbers 0, 1, 2, 3, 4 displayed diagonally on a yellow canvas, starting at (50, 50)

The five numbers drawn on top of each other at position (50, 50)

The for loop should use y++ and not y--, otherwise the loop never ends

offset should be declared inside draw() instead of outside it

rect() is missing its width and height arguments

function setup is missing its parentheses ()

Move the ellipse() call into setup() instead of draw().

Nothing is wrong; the code will work as is.

Declare and assign the variable before using it: let dotSize = 50; at the top of the code.

Replace dotSize with "dotSize" in quotes.

The text "a - b" displayed on the canvas

Nothing, text() cannot display the result of a subtraction

The number 18 displayed at position (150, 150)

The numbers 30 and 12 displayed separately

4 squares drawn on top of each other at position (60, 40)

5 squares drawn in a vertical column at x = 60

4 squares drawn in a horizontal row at y = 40

4 squares drawn in a vertical column at x = 60, spaced 80 pixels apart

multiplying two numbers requires a built-in p5.js function.

let cannot be used inside a custom function.

The function correctly calculates the area, but never displays it because text() is missing inside area().

area() cannot be called from inside draw().
