Of all the natural numbers, the only number which is quite different from the rest is '1'; also called

*numero uno*, it is the first number, which children learn to count. The identity property is concerned with the multiplication of a number by 1.*The product of any number and 1 is the same number.*"

In terms of equations, for a variable or number 'a', this property can be expressed as follows:

*a x 1 = a*

*times*the second number would be. That is, in this example,

*'a' times 1*, would be

*1 counted 'a' times*, which would give you 'a' again. Let me provide some examples of this property in the next section.

Examples

Understanding an actual worked out example is the best way to learn math. Here are some examples, which will clarify the concept:

- m x 1 = m
- 1 x 2/5 = 2/5
- 56 x 6 x 1 = 56 x 6
- 43.99 X 1 = 43.99
- (2 + 5) x 1 = (2 + 5)
- 1000000 x 1 = 1000000

*1 multiplied by any number, gives back the same number*'.
