Exponents compound, which is why they outrun intuition. Each increase of 1 in the exponent multiplies the result by 2 again — so the gap between 10 and 11 is larger than everything that came before it when the base exceeds 2.
How the Exponent Calculator works
Raising a base to a power, including the cases that confuse: a negative exponent is a reciprocal rather than a negative result, and anything to the power zero is 1. The page explains why in each case rather than just returning the number.

Frequently asked questions
What does a negative exponent mean?
A reciprocal, not a negative answer. 2⁻³ is 1 ÷ 2³ = 0.125. The sign of the exponent flips the operation; only a negative base makes the result negative.
Why is anything to the power zero equal to 1?
Because bⁿ ÷ bⁿ is both b⁰ and 1 at the same time, so they must be equal. It falls out of the division rule rather than being an arbitrary choice.
What is a fractional exponent?
A root. x^(1/2) is the square root and x^(1/3) is the cube root, so x^(2/3) is the cube root squared.
Why do exponents grow so fast?
Because each increase of 1 multiplies by the base again. With a base above 2, the jump from one exponent to the next exceeds everything that came before it.
