# MS-Excel Formulas

Excel can manipulate your data by using formulas. Formulas can be as simple as adding two or more numbers together or as complicated as determining the calculation of a second-order differential equation.

Formulas use data, stored in other cells, to calculate a new result that appears in another cell. To create even more complicated spreadsheets, you can even make a formula use data from other formulas so that changes in a single cell can ripple throughout an entire spreadsheet.
