Makes shopping discounts and tax calculations effortless.
- Example: 30% OFF a $49.80 item (Finding the discounted price)
👉 4980 - 30% = 3,486

👉 100 × 10% = 10

■ Constant Calculation (Casio style)
Simply tap the operator twice to set a constant.
- Example: When you want to add 100 as a constant (Enter 100++)
1000 = 1100
2000 = 2100
