What is 2 × 1?

Answer

2 × 1 = 2

2 × 1 = 2 — one of the 45 multiplication facts that the times tables hold. Below: the two divisions that undo it and the row it sits in.

Where the Answer Comes From

Multiplying by 1 leaves a number exactly as it was, so 2 × 1 is 2 without any adding at all. That property is why one is called the identity for multiplication.

The Factors Can Be Swapped

1 × 2 comes to the same 2, because multiplication is commutative. The two are read differently — 2 × 1 is 1 lot of 2, 1 × 2 is 2 lots of 1 — and that is what makes swapping them a way to check the answer rather than a restatement of it.

1 × 2 = 2

The Divisions That Undo It

Division undoes multiplication, so this one fact gives two of them, and each checks the other.

Where It Sits in the Tables

The same fact appears in two rows of the grid — in the 2 times table and in the 1 times table. Knowing one row therefore covers part of the other.

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. '2' and '1') to get the product, how it is built, the two divisions that undo it and the table row it belongs to.

2 × 1 = 2

Is 1 × 2 the same as 2 × 1?

Yes — both come to 2, because multiplication is commutative. They are read differently, though: 2 × 1 is 1 lot of 2, and 1 × 2 is 2 lots of 1.

What divided by what gives 2?

2 ÷ 2 = 1 and 2 ÷ 1 = 2. Division undoes multiplication, so each of these two checks the other.
