In this lesson I learned about simple formulas. A FORMULA is used to calculate numerical information within Excel. You can use CELL REFERENCES to create formulas. A cell reference links the cells content so that it can be used in calculations. There must be an EQUALS SIGN before any formula in order for it to be calculated in Excel. The cell reference and the actual cell are connected through color coordination.

The CELL ADDRESS is also used to determine which cell to use in your cell reference. POUND SIGNS may appear in a cell if its number is too large to fit within the cell. Excel used ORDER OF OPERATIONS when calculating formulas. You ca n override this by utilizing PARENTHESIS. You can edit a formula in the FORMULA BAR located below the ribbon.
