NCalc101 - Expressions

Expressions are the core of NCalc101. An expression is a combination of numbers, operators, variables, and functions that evaluates to a result.

Writing Expressions

• Type your expression in the input box, such as 3 + 4 * 2.
• Use parentheses to control the order of operations: (3 + 4) * 2.
• Expressions can include variables and functions for more advanced calculations.

Supported Operators

• + Addition
• - Subtraction
• * Multiplication
• / Division
• ^ Exponentiation (e.g., 2^3 = 8)
• Parentheses ( ) for grouping

Using Functions

NCalc101 supports many built-in functions. For example:

• sqrt(16) returns 4
• sin(3.14) returns the sine of 3.14 radians
• log(100) returns the natural logarithm of 100

Examples

• 5 * (2 + 3) evaluates to 25
• sqrt(9) + 4 evaluates to 7
• 2^4 - 6 evaluates to 10

Tips

• Check your expression for typos before evaluating.
• Use the Examples page for more sample expressions.
• Combine variables and functions for powerful calculations.

Mastering expressions is the key to getting the most out of NCalc101!
