Multiplication Facts

Property 1: 12538 × 1 = 12538, 1 × 12538 = 12538

1234567 × 1 = 1234567, 1 × 1234567 = 1234567

Product of any number and 1 is that number itself.

Let A be any number. Then

A × 1 = A. Also 1 × A = A.

Property 2: 234 × 782 = 182988 782 × 234 = 182988

We get the same product in both cases.

The product of two numbers is the same even if the
order of numbers is changed.

So, we can interchange the multiplier and multiplicand.

Let A and B be the two numbers then

A × B = B × A
