Scientific Calculator

A scientific calculator is an electronic tool built specifically for math, science, and engineering work. It goes way beyond adding and subtracting. It can solve problems involving angles, powers, and complex formulas.

Modern scientific calculators pack many useful features. Most include:

• Trigonometric functions (sin, cos, tan and their inverses)
• Logarithmic and exponential functions (log, ln, e^x, 10^x)
• Roots and powers (square root, cube root, x^y)
• Fraction handling and conversion
• Memory buttons (M+, M-, MR, MC) to store values
• Degrees/radians/gradians modes
• Scientific notation support
• Percentage and factorial (!) calculations

Basic operations work almost the same as on any calculator. Type or click numbers and symbols like +, -, ×, ÷. Always follow the order of operations—parentheses first, then exponents, multiplication/division, and addition/subtraction.

For example, to calculate (5 + 3) × 2, enter the parentheses carefully. Most scientific calculators respect the order automatically when you use brackets.

Practice here: Try 12 + 8 ÷ 4. The correct answer is 14, not 5, because division happens before addition. Use the calculator on this page to verify. It supports both button clicks and keyboard input for convenience.

Clear the screen with AC or C when starting fresh. Many tools also have a backspace or delete key to fix mistakes without clearing everything.
