Important Formulas and Concepts in CBSE Class 2 Mathematics



Addition:
- The sum of two or more numbers is the total amount obtained when they are combined together.
- The symbol used for addition is '+'. For example, 2 + 3 = 5.

Subtraction:
- Subtraction is the process of finding the difference between two numbers.
- The symbol used for subtraction is '-'. For example, 5 - 3 = 2.



Multiplication:
- Multiplication is the process of repeated addition.
- The symbol used for multiplication is '×' or '*'. For example, 2 × 3 = 6.

Division:
- Division is the process of sharing or distributing a given quantity into equal parts.
- The symbol used for division is '÷' or '/'. For example, 6 ÷ 3 = 2.



Ascending Order:
- Numbers arranged from the smallest to the largest are in ascending order.

Descending Order:
- Numbers arranged from the largest to the smallest are in descending order.

Number Patterns:
- Number patterns are a sequence of numbers that follow a certain rule or pattern.
- For example, counting in multiples of 2: 2, 4, 6, 8, 10, ...



2D Shapes:
