By name: math-tens description: Performs basic arithmetic (add, subtract, multiply, divide) and rounds results to the nearest multiple of 10. Use for calculations that need clean multiples of 10. argument-hint: [operation] [number1] [number2]
Arithmetic with Multiples of 10
Perform basic arithmetic operations and round the result to the nearest multiple of 10.
Input
The operation and numbers are provided as: $ARGUMENTS
Expected format: [operation] [number1] [number2]
Supported Operations
| Operation | Aliases | Example |
|---|---|---|
| Addition | add, + |
add 15 27 |
| Subtraction | subtract, sub, - |
subtract 100 55 |
| Multiplication | multiply, mul, * |
multiply 6 7 |
| Division | divide, div, / |
divide 100 3 |
Rounding Logic
Results are rounded to the nearest multiple of 10 using standard rounding:
- 0-5 rounds down (44 → 40)
- 6-9 rounds up (45 → 50, 47 → 50)
Formula: round(result / 10) * 10
Output Format
Show both the raw calculation and the rounded result:
Operation: [operation] [num1] [num2]
Raw result: [exact result]
Rounded to nearest 10: [multiple of 10]
Examples
| Input | Raw Result | Rounded Result |
|---|---|---|
add 23 19 |
42 | 40 |
subtract 100 55 |
45 | 50 |
multiply 7 8 |
56 | 60 |
divide 100 3 |
33.33... | 30 |
add 5 0 |
5 | 10 |
multiply 10 10 |
100 | 100 |
Edge Cases
- Division by zero: Return an error message explaining division by zero is undefined
- Missing arguments: Ask the user for the complete operation (operation, number1, number2)
- Invalid operation: List the supported operations and ask user to try again
- Non-numeric input: Ask the user to provide valid numbers
- Negative results: Round toward zero for negative numbers (-44 → -40, -45 → -50)
