You include the cells in parenthesis that you want it to average. The shortcut function in Excel you could use in its place is =AVERAGE(C4:F4). When we calculated the average, we used a formula that was created from scratch. See Figure 4.įigure 4 Calculate Average, Maximum, Minimum Your amount will be 73.5, which is 5% higher than the current North division total in cell G4. In cell I4 (that’s the letter capital I followed by 4), enter =G4*105% and hit enter. To get that, you need to multiple the division totals times 105%. For our example, you can find the division totals with a projected increase of 5%. To Multiply within a cell, use the * asterisks symbol. You need to use the parenthesis around the addition part so that Excel will do that calculation first. In cell H4, type the following formula: =(C4+D4+E4+F4)/4 and hit enter. Multiplication and DivisionĬreate an average formula using the parenthesis, division symbol, and addition symbol. Subtraction is the same as addition, except you use the subtraction symbol (-). In this case from cells C4 through cell F4. The sum function adds whatever cells are in the parenthesis. The function to do addition is =SUM(C4:F4). If not, then you can copy and paste the formula from G4 into the total cells for the other divisions. Depending on the version of Excel you are using, it may even copy the formula down for you to cells G5, G6, and G7. In cell G4, enter the formula =C4+D4+E4+F4 and hit enter. For example, you can add the total for four quarters. Use the operation symbols within the formula:Ĭreate a formula just as you would say it. To begin using math in Excel, start with the basics. For example, B1:B5 is cells B1 through B5. If you are using a function (formulas that Excel has pre-built for you), the colon (:) allows you to reference a range of cells.Use parenthesis () around any part of the formula that you want Excel to do first.If you change A1 or B2, Excel will re-calculate for you. A1 and B2 are the cell references (essentially the names of the cells). For example, =A1+B2 would add the items in cells A1 and B2. Use cell references in the formulas to tell Excel which one to use.Start each formula with an equal sign symbol (=).Below are a few real-life business examples of how math could be made easier by simply opening Excel and using the functions available. Do your employees realize how much time they could be saving by doing math in Excel? They could be more efficient and successful if they used basic Excel functions to handle math problems.
