BINARY NUMBERS (BASE 2 NUMBERS)

  • Addition in base 2
  • Subtraction in base 2
  • Multiplication & Division in base 2

 

ADDITION IN BASE TWO

We can add binary numbers in the same way as we separate with ordinary base 10 numbers.

The identities to remember are:-

0 + 0 = 0, 0 + 1 = 1, 1 + 0 = 1, 1 + 1 = 10, 1 + 1 + 1 = 11, 1 + 1 + 1 + 1 = 100

 

Worked Examples

Simplify the following

  1. 1110 + 1001 2.         1111 + 1101 + 101

Solutions:

 1.  1110+100110111

 

2.    1111        1101 + 101100001

 

Note: 11 take 1 carry 1

10 take 0 carry 1

100 take 0 carry 10

 

 

EVALUATION

  1. Simplify the following 101 + 101 +111
  2. 10101 + 111

 

 

ADDITION IN BICIMALS

In bicimals, the binary point is placed underneath each other exactly the same way like ordinary decimals.

 

Example:

  1. 1.1011two +   10.1001two  +  10.01
  2. 10.001two+ 101.111

 

Solution:

 

1)            1.1011             10.1001  +  10.0100110.1000two2)       101.111     +10.0011000.000

SUBTRACTION IN BASE TWO

The identities to remember on subtraction are: 0 – 0 = 0, 1 – 0 = 1, 10 – 1 = 1, 11 – 1 = 10, 100 – 1 = 11

Worked Examples

Simplify the following:-

(a)      1110 – 1001

Solutions:

(a) 1110 1001101

 

SUBTRACTION IN BICIMAL

Example

101.101two – 11.011two

solution:101.10111.01110.010

 

EVALUATION

  1. 10111÷110
  2. 10001 x 11
