What Does Each Key Do?
sin, cos, tan — Trigonometric functions. Used for angles (e.g. finding a triangle's side length).
DEG / RAD — Switches whether angles are measured in Degrees (0–360°) or Radians (0–2π). Most school problems use Degrees.
log — Logarithm base 10. Answers "10 to what power gives this number?"
ln — Natural logarithm (base e ≈ 2.718). Common in higher-level math and science.
√ (sqrt) — Square root of the current number.
x² — Squares the current number (multiplies it by itself).
π (pi) — Inserts the mathematical constant π ≈ 3.14159, used in circle/angle calculations.
e — Inserts Euler's number ≈ 2.71828, the base of natural logarithms.
n! — Factorial. Multiplies the number by every whole number below it down to 1 (e.g. 5! = 5×4×3×2×1 = 120).
MC / MR / M+ — Memory Clear, Memory Recall, Memory Add. Store a number temporarily to reuse in a later calculation.
( ) — Parentheses, for controlling the order of operations (like in written math).
% — Converts the current number to a percentage (divides by 100).
