15 + 20 = 35
2. Subtraction Formula
Result=A−B
Example
If:
A = 50
B = 12
Result:
50 − 12 = 38
3. Multiplication Formula
Result=A×B
Example
If:
A = 7
B = 8
Result:
7 × 8 = 56
4. Division Formula
Result=BA
Example
If:
A = 100
B = 5
Result:
100 ÷ 5 = 20
Note: Division by zero is not allowed because it is mathematically undefined.
AA Calculator Examples
The following examples demonstrate how the calculator works.
| First Value | Second Value | Operation | Result |
|---|---|---|---|
| 12 | 8 | Addition | 20 |
| 50 | 15 | Subtraction | 35 |

Understanding Each Arithmetic Operation
Addition
Addition combines two or more values into a single total.
Common Uses
- Calculating expenses
- Adding test scores
- Summing sales figures
- Budget planning
Example
If you spend:
- $25 on groceries
- $40 on fuel
Total spending:
25 + 40 = 65
Subtraction
Subtraction finds the difference between two values.
Common Uses
- Tracking remaining budget
- Measuring changes
- Inventory management
- Determining profit or loss
Example
If your account contains $500 and you spend $150:
500 − 150 = 350
Remaining balance = $350
Multiplication
Multiplication calculates repeated addition.
Common Uses
- Product pricing
- Area calculations
- Salary estimations
- Bulk quantity calculations
Example
If one item costs $12 and you buy 8:
12 × 8 = 96
Total cost = $96
Division
Division splits a quantity into equal parts.
Common Uses
- Cost sharing
- Average calculations
- Unit price analysis
- Resource allocation
Example
If a bill of $120 is shared among 4 people:
120 ÷ 4 = 30
Each person pays $30.
