A4. Real numbers : reciprocals.
The reciprocal of any number n is 1/n.
For example:
The reciprocal of 8 is 1/8 |
|
Any non-zero number multiplied by its
reciprocal is 1

For example:
6 x 1/6=1, 13 x 1/13=1 |
So, the reciprocal of any number is its multiplicative
inverse, but zero has no reciprocal, because division by zero is not defined.
