Features of the Online Calculator
Basic Maths and Decimals
Handle addition, subtraction, multiplication and division. Use the decimal point for prices, measurements and other values that are not whole numbers. The plus/minus button changes a number between positive and negative.
Brackets for Calculations
Use brackets to show which part of a calculation should happen first. For example (8 + 2) × 3 gives 30. This is helpful when a question includes more than one operation.
History, Copy and Paste
Open History to review earlier calculations. Copy lets you reuse an answer, while Paste helps you bring a copied value into the calculator. These options can save time when working through a list of figures.
Color Themes and Fullscreen
Choose from the available color themes to change the calculator’s appearance. Open fullscreen mode when you want more space to focus on the numbers.
Percentages, Squares and Square Roots
The % button divides a value by 100. For example 20% becomes 0.2. To find 20% of 150, calculate 150 × 20 ÷ 100.
Use x² to square a number, √ to find its square roo, and 1/x to find its reciprocal.
Memory Buttons
The online calculator includes memory controls for keeping a value while you work:
- M+: Add a value to memory.
- M−: Subtract a value from memory.
- MR: Recall the stored value.
- MC: Clear the stored value.
These buttons are useful when you need the same number during several calculations.
