This guide explains how to use all features of the Casio-style Scientific Calculator with examples for each function.
Basic Operations of Casio Scientific Calculator Online
1. Number Input
- Click number buttons (0-9) to enter digits
- Example: To enter 45, click
4 then 5
2. Decimal Point
- Click
. to add decimal places - Example:
3 . 1 4 → 3.14
3. Clear Functions
| Button | Action | Example |
|---|
| AC | Clear all (reset calculator) | Clears current calculation |
Basic Calculations
4. Arithmetic Operations
| Button | Operation | Example Input | Result |
|---|
| + | Addition | 5 + 3 = | 8 |
| - | Subtraction | 9 - 4 = | 5 |
| × | Multiplication | 6 × 2 = | 12 |
| ÷ | Division | 8 ÷ 2 = | 4 |
5. Percentage (%)
- Calculates percentage of current value
- Example:
50 + 10 % = → 55 (adds 10% of 50)
50 - 10 % = → 45 (subtracts 10%)
6. Sign Change (±)
- Toggles between positive/negative
- Example:
5 ± → -5
Scientific Functions

| cos | Cosine | 60 cos | 0.5 |
| tan | Tangent | 45 tan | 1 |
8. Powers & Roots
| Button | Function | Example Input | Result |
|---|
| x^y | Power | 2 x^y 3 = | 8 (2³) |
| √ | Square root | 9 √ | 3 |
| 10^x | Power of 10 | 2 10^x | 100 |
9. Logarithms
| Button | Function | Example Input | Result |
|---|
| log | Base-10 log | 100 log | 2 |
| ln | Natural log | 7.389 ln | ~2 |
10. Constants
| Button | Value | Example Usage |
|---|
| π | Pi (3.14159…) | π × 2 = → 6.283 |
11. Factorial (!)
- Calculates n!
- Example:
5 ! → 120 (5×4×3×2×1)
Memory Functions
| Button | Function | Example |
|---|
| M+ | Add to memory | 5 M+ adds 5 to memory |
| M- | Subtract from memory | 3 M- subtracts 3 |
| MR | Recall memory | Displays stored value |
| MC | Clear memory | Resets to 0 |
Memory Example:
5 M+ (stores 5)3 M+ (memory = 8)MR → shows 8MC → resets to 0
Advanced Usage of Casio Scientific Calculator Online
Parentheses ()
- For complex calculations
- Example:
( 2 + 3 ) × 4 = → 20
Keyboard Support
- Type numbers/operators directly:
5 * 3 Enter → 15
4 ^ 2 = → 16
Esc clears all
Tips:
- Use AC to completely reset
- Chain calculations:
5 + 3 = × 2 = → 16 - For scientific notation:
1.23 × 10^4 → Enter as 1.23 10^x 4
