What is 9 × 9?
Answer
9 × 9 = 81
9 × 9 = 81 — one of the 45 multiplication facts that the times tables hold. Below: the addition behind it, the division that undoes it and the row it sits in.
Where the Answer Comes From
Multiplying is adding the same number over and over: 9 × 9 is 9 lots of 9.
9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 = 81
The Divisions That Undo It
Division undoes multiplication, so this fact gives one division back — both factors are the same number.
Where It Sits in the Tables
A square sits on the diagonal of the grid: it appears once, in the 9 times table, rather than twice like the other facts.
