 # Numbers In Base Two II

Welcome to Class !!

In today’s Mathematics class, We will be looking at Multiplication and Division in Base Two. We hope you enjoy the class! #### MULTIPLICATION AND DIVISION IN BASE TWO

In multiplication, 0 x 0 = 0, 1 x 0 = 0, 1 x 1 = 1.

When there is long multiplication of binary numbers, the principle of addition can be used to derive the answer. Under division, the principle of subtraction can be used.

Worked Examples:

1. 1110 x 111

Solution:

1. Multiply 11.01 by 1.1 in base two

Solution:

##### DIVISION IN BASE TWO

Example:

Divide 110010101 by 1111

Solution:

1100101012  ÷  11112 = 110112

Example:

Find the square root of 10100012

Solution:

First convert it to base 10

10100012 = 1 x 2 6+ 0 + 1 x 2 4+ 0 + 0 + 0 + 1 x 20

= 64 + 16 + 1 = 81ten

The square root of 81 = 9ten

2 |  9       1

2 |  4       0

2 |  2       0

2 |  1     1

0 |  0

= 10012

EVALUATION

1. 10111÷110
2. 10001 x 11

We have come to the end of this class. We do hope you enjoyed the class?
