Numbers In Base Two II

Back to: MATHEMATICS JSS3

 

Welcome to Class !!

We are eager to have you join us !!

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:

$$\begin{gathered} 1) 1110 \\ \times \frac{110}{0000} \\ 1110 \\ \frac{1110}{1010100} \end{gathered}$$

 

2. Multiply 11.01 by 1.1 in base two

Solution:

$$\begin{gathered} 1101 \\ \frac{x 11}{1101} \\ \frac{ 1101}{100.111} \end{gathered}$$

 

 

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 = 81_ten

The square root of 81 = 9_ten

 

2 |  9       1

2 |  4       0

2 |  2       0

2 |  1     1

0 |  0

= 1001₂

 

 

EVALUATION

1. 10111÷110
2. 10001 x 11
