Algebra
1.What is Algebra- Algebra is a branch of mathematics that
uses letters, symbols and numbers to represent relationships
and solve problems. The letters used in algebra are called
variables, and they stand for unknown values. Algebra helps
us generalize arithmetic and is widely used in science,
engineering, economics and in daily life.
2.Basic terms in Algebra-
2.1 Variables-
A variable is a symbol (usually a letters like- X,Y and A) that
represents an unknown number.
Example-
If x = 5, then x + 3 = 8
2.2 Constants-
A constant is fixed numerical value.
Example-
In the Expression- 3x + 7, the number 7 is a constant.
