what is the formula for subtraction in excel

You can also use a concatenate formula to combine cell values. For example, if cell A1 had a first name and cell B1 had a last name, you could enter =A1&' '&B1, which combines A1 with B1, with a space between each value. You could also create a formula that would make one cell equal to more than one value. For example, if you were to enter =A1 in B1, whatever value was in A1 would automatically be placed in B1. Finally, we manually enter a times ( * ) formula using the sum function to find the value of 5 * 100.Īn = ( equals) creates a cell equal to another. Next, we show how you can manually enter a formula, and then using a mouse, get the cell values (you can also highlight multiple cells to create a range). In our first formula entered into the cell 'D1,' we manually enter a =sum formula to add 1+2 (in cells A1 and B2) to get the total of '3.' With the next example, we use the mouse to highlight cells A2 to D2 and then click the formula button in Excel to automatically create the formula. Formulas are created using relative cell reference by default, and if you add a dollar sign ($) in front of the column or row, it becomes an absolute cell reference.īelow is an animated visual example of how an excel formula can be inserted into a spreadsheet.For example, A1:A10 is cells A1 through A10. Using the colon (:) lets you get a range of cells for a formula.Math functions or calculations can use an operator, including plus (+), minus (-), multiply (*), divide (/), greater than (>), and less than (<). If a math function is being performed, like addition, subtraction, and multiplication, the math formula is surrounded in parentheses.The function tells the spreadsheet the type of formula. After the equal symbol, either a cell or formula function is entered.All spreadsheet formulas begin with an equal sign (=) symbol.

For example, you could have a total cell that adds all values in a column. By creating formulas, you can perform quick calculations even if the information changes in the cells relating to the formula. Formulas are what helped make spreadsheets so popular.
