Computer Calculator

Introduction for computer algebra calculator:

Algebra is a incorporated from mathematics. Algebra plays vital role in our regular life. Computer algebra calculator will perform the arithmetic operations such as addition, subtraction, multiplication and division. Computer algebra calculator will handle following terms such as variables, constant, coefficients, exponents, terms and expressions. Computer algebra will use the symbols and alphabets in the place of unknown values. Computer algebra calculator is used for cross checking by the students. Therefore, students are using computer algebra calculator for their studies.
Example Problems for Computer Algebra Calculator:

Computer algebra calculator

Example 1:

Solve the equation for x, x + 120 = 116.

Solution:

x + 120 = 116 (add -120 on both sides)

x + 120 120 = 116 120

x = -4

Example 2:

Solve the equation for x, 107 +2x = 117.

Solution:

107 + 2x = 117 (add -107 on both sides)

107 – 107 + 2x = 117 107

2x = 10 (divide both sides by 2)

‘(2x)/2′ = ’10/2’

x = 5

Example 3:

Solve the equation for x, 15x = 155.

Solution:

15x = 155 (divide both sides by 15)

‘(15x) /15’ = ‘155/15’

x = 10.33

Example 4:

Solve the equation for x, 4x + 11 = 119 + 2x.

Solution:

4x + 11 = 119 + 2x (add -11 on both sides. So we get,)

4x + 11 11 = 119 – 11 + 2x

4x = 108 + 2x (add -2x on both sides. So we get,)

4x 2x = 108 + 2x 2x

2x = 108

‘(2x)/2’ = ‘108/2’

x = 54.

Example 5:

Multiply the following terms (5x) ( 118x + 119).

Solution:

(5x) (118x + 119)Now we have to multiply 5x with 118x + 119 like below.

= (5x ‘xx’ 118x) + (5x ‘xx’ 119) Note: (‘a^m’ ) (‘a^ n’ ) = ‘a^(m + n)’

= 590’x^2′ + 595x

Example 6:

Multiply the following terms (’15x^4′ ) (’16x^5y^6′ ).

Solution:

(’15x^4′ ) (’16x^5y^6′ ). we have to multiply ’15x^4′ with ’16x^5y^6′ like below.

= ’15x^4 xx 16x^5y^6′

= ‘(15 xx 16) (x^4 xx x^5) (y^6)’ Note: ‘(a^m) (a^ n) = a^(m + n)’

= 240 ‘(x^(4 + 5)) (y^6)’

= 240’x^9 y^6′
