While studying, the important points to remember from Class 9 Maths are as follows:

- A number is a mathematical object that can be counted and measured.
- A number system is a collection of values that are used to represent a quantity.
- The whole numbers are a collection of natural numbers that include zero.
- A variable is a symbol that has no fixed numerical value.
- A point is something that does not play a role.
- A line’s ends are called points.
- A straight line is one that is parallel to all of its points.
- A surface is defined as having only length and width.
- A surface’s edges are lines.
- A plane surface is one that lies evenly with straight lines on it.
- Some of the algebraic identities are as follows:
- (a + b)
^{2}= a^{2}+ 2ab + b^{2} - (x – a) (x + b) = x
^{2}+ (b – a) x – ab

- (a + b) (a – b) = a
^{2}-b^{2} - (x + a) (x + b) = x
^{2}+ (a + b) x + ab - (a – b)
^{2}= a^{2}– 2ab + b^{2} - (x + a) (x – b) = x
^{2}+ (a – b) x – ab

- (x – a) (x – b) = x
^{2}– (a + b) x + ab

- (a + b)
- Area of parallelogram = Base × Height
- Area of a circle (of radius r) = π × r
^{2} - The diameter of the circle, d = 2 × r
- Circumference of the circle = 2 × π × r
- (Hypotenuse)
^{2}= (Perpendicular)^{2}+ (Base)^{2}
