We have listed a few points to remember for Class 8 Mathematics Chapter 9 that students can refer to while practising.

- The letters which are used to represent numbers are called literal numbers or literals.
- A combination of constants and variables connected by the signs of fundamental operations of addition, subtraction, multiplication, and division is called an algebraic expression.
- Various parts of an algebraic expression which are separated by the signs of ‘++’ or ‘−-’ are called the terms of the expression.
- Some standard identities are,

(i) (*a*+*b*)2=*a*2+*b*2+2*ab*(a+b)2=a2+b2+2ab

(ii) (*a*−*b*)2=*a*2+*b*2–2*a**b*(a−b)2=a2+b2–2ab

(iii) (*a*+*b*)(*a*−*b*)=*a*2–*b*2
