This document discusses formulas in Excel and how they allow calculations using mathematical operators and cell references. Formulas use operators like +, -, *, and / to perform calculations on numbers within cells, such as adding the values in cells A1 and B1. Common operators include those for addition, subtraction, multiplication, division, squaring, and square roots. Formulas can calculate numbers alone, cell values alone, or cell values combined with numbers.
