What this means, in plain words
Inverse operations undo each other: addition and subtraction, multiplication and division.
Addition puts amounts together to find a total. Subtraction takes one amount away, or finds the difference between two.
Representing means showing the same maths another way, with objects, a picture or a bar model, so the structure becomes visible.
