Used Formulas: ,
A formula is an equation that performs operations on worksheet data. You can use an Excel 2010 formula to perform mathematical operations, such as addition and multiplication, or they can compare worksheet values, join text, averaging a student's test results etc. Formulas can refer to other cells on the same worksheet, cells on other sheets in the same workbook, or cells on sheets in other workbooks. In addition, if you change the data in your speadesheet, Excel will automatically recalculate the answer without you having to re-enter the formula, A basic formula format will start with an equals sign (=)followed by one or more operands, separated by one or more operators. Operandscan be values, text, cell reference, ranges, defined names, or function names. Operators are symbols used to represent the various arithmetic and comparison operations you can perform on the operands.
In Microsoft Excel 2010, operators are executed in this order :
In Microsoft Excel 2010, operators are executed in this order :
- Parenthesis. ()
- Percent. %
- Exponentiation. ^
- Multiplication. *
- Division. /
- Addition. +
- Subtraction. -
- Concatenation (putting string together, like Jenn & ifer) . &
- Equal To. =
- Greater Than. >
- Less Than. <
- Place the cursor in the cell where the formula will appear, I. e. E5.
- Enter an =sign. All Excel formulas start with the 'equal'sign.
- Enter the expression that will produce the result you want. This can consist of operands, values, variables, and symbols which represent mathematical procedures such as + or - to add and subtract, e. g. A5+C5.
- When the formula is complete, press Enter. The result of the formula will be calculated and displayed in the cell E5.
- You can see the formula in the Formula bar at the top of the screen the cell pointer on the cell E5.
- If there is an error in a formula, an error message is displayed which will begin with a # sign. When writing formulas it is easy to make a mistake. Here are some common mistakes;
