What is 1 × 5?
Answer
1 × 5 = 5
1 × 5 = 5 — 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 1 × 5 is 5 without any adding at all. That property is why one is called the identity for multiplication.
The Factors Can Be Swapped
5 × 1 comes to the same 5, because multiplication is commutative. The two are read differently — 1 × 5 is 5 lots of 1, 5 × 1 is 1 lot of 5 — and that is what makes swapping them a way to check the answer rather than a restatement of it.

The Divisions That Undo It
Where It Sits in the Tables
The same fact appears in two rows of the grid — in the 1 times table and in the 5 times table. Knowing one row therefore covers part of the other.

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

What is 1 × 5?
1 × 5 = 5
Is 5 × 1 the same as 1 × 5?
Yes — both come to 5, because multiplication is commutative. They are read differently, though: 1 × 5 is 5 lots of 1, and 5 × 1 is 1 lot of 5.
What divided by what gives 5?
5 ÷ 1 = 5 and 5 ÷ 5 = 1. Division undoes multiplication, so each of these two checks the other.
