What is 1 × 1?
Answer
1 × 1 = 1
1 × 1 = 1 — one of the 45 multiplication facts that the times tables hold. Below: the division that undoes it and the row it sits in.
Where the Answer Comes From
Multiplying by 1 leaves a number exactly as it was, so 1 × 1 is 1 without any adding at all. That property is why one is called the identity for multiplication.
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 1 times table, rather than twice like the other facts.

About "Multiplication Facts" Calculator
Multiplying by one is the case where nothing is added at all: the other number is already the answer. Enter two numbers from 1 to 9 (e.g. '1' and '1') to get the product, how it is built, the division that undoes it and the table row it belongs to.
