Perform 2×2 and 3×3 matrix operations — add, subtract, multiply, determinant, inverse, transpose, and scalar multiply.

Solve Ohm's law, kinematics (SUVAT), force, kinetic energy, and convert scientific units — pressure, energy, force, frequency, power.

Parse chemical formulas, compute molar mass, and convert between mass, moles, and molecule count.

Calculate a percentage of any number, plus the value after adding or subtracting that percent.

Simplify ratios and scale either side while keeping the same proportion.
