Scientific Calculator

How to use the scientific calculator

Type an expression directly, or tap the keypad. The calculator follows standard order of operations: parentheses first, then powers, then multiplication and division, then addition and subtraction. Implicit multiplication works too, so 2(3+4) is read as 2 × (3 + 4).

Supported functions

• Trigonometry: sin, cos, tan and their inverses asin, acos, atan — in degrees or radians.
• Logarithms: log (base 10), ln (natural log) and exp for e raised to a power.
• Powers and roots: ^ for any power, x² for squares, √ for square roots.
• Other: reciprocal (1/x), absolute value, factorial (5!), percent, π and e.

Worked examples

• sin(30) in degrees mode returns 0.5.
• 2^10 returns 1024, and 5! returns 120.
• log(1000) returns 3; ln(e) returns 1.
• (2+3)*4 - 10/2 returns 15.

Keyboard shortcuts

Numbers and operators type straight into the display. Press Enter or = to calculate, Backspace to delete the last character, and Escape to clear everything.
