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.

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 + 5Term
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 ( + )
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
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 + 5Examples 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
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
+ (-3x+3) = 2
-3x + 3 = 2
Subtract 3 on both sides,
-3x + 3 -3 = 2-3
-3x=-1
x =1/3
- (-3x+3) = 2
3x-3 =2
Add 3 on both sides
3x-3+3=2+3
3x=5
x=5/3
