Glossary of Algebraic Symbols

Algebra is a branch of mathematics. Algebra plays an important role in our day to day life. The glossary of algebraic symbols involved in the four basic operations such as addition, subtraction, multiplication and division. The most important terms with the glossary of algebraic symbols are variables, constant, coefficients, exponents, terms and expressions. In Algebra, besides numerals we use symbols and alphabets in place of unknown numbers to make a statement. Hence, glossary of algebraic symbols may be regarded as an extension of Arithmetic.

Most important terms for glossary of algebraic symbols:


Expressions
          An algebraic Expression is the combination of variables, constant, coefficients, exponents, terms which are combined by the following arithmetic operations Addition, subtraction, multiplication and division. The example of an algebraic expression is given below
                           2y + 5
Term
          Terms of the algebraic expression is concatenated to form the algebraic expression by the arithmetic operations such as addition, subtraction, multiplication and division. In the following example 3n2 + 2n the terms 3n2, 2n are combined to form the algebraic expression 3n2 + 2n by the addition operation ( + )

Coefficient
          The coefficient of an algebraic expression is the value is present just before the terms. From the following example, 3n2 + 2n the coefficient of 3n2 is 3 and 2n is 2

Equations
          An algebraic equation equals the numbers or expressions. Most probably algebraic equation is used for the value of the variable. The example of the equation is given below
                          2y + 5

Examples for glossary of algebraic symbols:


Example 1:
8x - 3 = 2x
Solution:
8x - 3 = 2x
8x – 3 + 3 =2x + 3 (Add 3 on both sides)
8x =2x +3
8x – 2x =2x -2x + 3 (Add -2x on both sides)
6x = 3
6x /6 = 3 / 6  (both sides by divided 6)
X = 1/2

Example 2:
Solve the equation |-3x + 3| -8 = -6
Solution:
|-3x + 3| -8 = -6
|-3x + 3| -8 + 8 = -6 + 8 (Add 8 on both sides)
|-3x + 3| = 2

Case (i)
+ (-3x+3) = 2
-3x + 3 = 2 
Subtract 3 on both sides,
-3x + 3 -3 = 2-3
-3x=-1
x =1/3


Case (ii)
- (-3x+3) = 2
3x-3 =2
Add 3 on both sides
3x-3+3=2+3
3x=5

x=5/3
