# Multiplication

For floating point multiplication, we decode the number and then carry out the following steps:
- Multiply the mantissae to get the mantissa
- Add the exponents to get the exponent
- Add the signs to get the sign

Let's illustrate with an example, using our [$8$-bit floating point representation](https://www.educative.io/courses/number-systems-for-computer-scientists/floating-point-representation).
