Points on a coordinate grid, step by step
One first-quadrant grid with four points marked on it, and four questions beside it: what is A?
The question
A=
Point A
- Start at the corner where the two lines meet — that is (0, 0), and every reading begins there.
- Along the bottom FIRST: count 0 across. Always this one before the other, because until you have gone along you do not know which line to go up.
- Then up: count 5. Now the two numbers have been used in the order they are written.
- So point A is (0, 5). Swap the two round and you would be at (5, 0) — somewhere else entirely, which is why the order is the whole of this.
How it works.
