Supports negative and fractional exponents
Exponents (also called powers) are a fundamental concept in mathematics representing repeated multiplication. They appear everywhere from compound interest calculations to scientific notation, making them essential for students, professionals, and anyone working with numbers.
In the expression an, ’a’ is the base (the number being multiplied) and ’n’ is the exponent (how many times to multiply). For example, 23 = 2 × 2 × 2 = 8.
Large and small numbers are expressed using powers of 10. For example, 5,000,000 = 5 × 106and 0.0003 = 3 × 10-4. This makes it easier to work with very large or very small values.
