Addition Formula Explained
Addition is the process of combining two or more numbers to get a total sum.
Formula:
A + B = Result
Where:
- A = First number
- B = Second number
- Result = Sum of A and B
Example:
If:
- A = 20
- B = 30
Then:
20 + 30 = 50
Subtraction Formula Explained
Subtraction is the process of finding the difference between two numbers.
Formula:
A − B = Result
Where:
- A = First number
- B = Second number
- Result = Difference
Example:
If:
- A = 100
- B = 40
Then:
100 − 40 = 60
