Basic Mathematical Operations
1. Addition (যোগ)
Addition is the process of combining two or more numbers.
a + b = c
Example:
25 + 15 = 40
Therefore, the answer is 40.
2. Subtraction (বিয়োগ)
Subtraction is the process of finding the difference between two numbers.
a − b = c
Example:
50 − 20 = 30
Therefore, the answer is 30.
3. Multiplication (গুণ)
Multiplication is a repeated addition of the same number.
a × b = c
Example:
12 × 5 = 60
Therefore, the answer is 60.
4. Division (ভাগ)
Division is the process of distributing a number into equal parts.
a ÷ b = c
Example:
100 ÷ 4 = 25
Therefore, the answer is 25.
5. Percentage (শতকরা)
Percentage represents a number as a fraction of 100.
Percentage =
Part ÷ Total
× 100
Example:
Percentage = (25 ÷ 100) × 100
= 25%
6. Power (ঘাত)
A power indicates how many times a number is multiplied by itself.
a² = a × a
Example:
5² = 5 × 5
= 25
