Basic & Scientific — two powerful calculators in one place.
Tap numbers and operators to build your expression. Memory buttons: M+ adds to memory, M− subtracts, MR recalls, MC clears. Full keyboard support. History stores last 20 calculations.
Access trig (sin/cos/tan + inverses + hyperbolic), logarithms (log/ln/log₂), powers, roots (√, ³√, xʸ), factorials, constants (π, e), random numbers, and ANS (last answer). Toggle DEG/RAD and HYP mode.
Scientific calculators handle advanced math — trig, logarithms, exponentials, hyperbolic functions, and factorials — used in engineering, physics, chemistry, and higher mathematics.
Standard deviation measures how spread out numbers are from the mean. A low value means data is clustered close to the average; a high value means it is widely spread.
DEG (degrees) and RAD (radians) are two units for measuring angles. A full circle = 360° = 2π radians. Most everyday use is in degrees; radians are standard in higher mathematics and physics.
