📊【Useful Calculation Examples】

■ Percentage (%) & Discount Calculations

Makes shopping discounts and tax calculations effortless.

- Example: 30% OFF a $49.80 item (Finding the discounted price)

👉 4980 - 30% = 3,486

- Example: Finding 10% sales tax on a $100.00 item

👉 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

- 5 ×× = 25 / = 125 / = 625
