Calculate powers and exponents with support for positive, negative, and fractional exponents
An exponent represents how many times a number (the base) is multiplied by itself. The expression bn means "b multiplied by itself n times." Exponents are fundamental in mathematics, science, and engineering for expressing very large or very small numbers efficiently.
Calculate investment growth using A = P(1 + r)t where the exponent represents time periods
Model exponential population changes using P = P₀ert for continuous growth rates
Binary systems use powers of 2 extensively, from memory sizes (210 bytes = 1 KB) to algorithm complexity
Express very large or small numbers efficiently, like 6.02 × 1023 (Avogadro's number)
Many physical laws involve exponents, such as inverse square laws (intensity ∝ 1/r2)
pH calculations use logarithms and exponents to measure acidity (pH = -log₁₀[H+])
Calculate percentages and percentage changes
Calculate percentage increase
Calculate percentage decrease
