Tech Fact
Excel 2016 follows BEDMAS rule for doing mathematical calculations, where B stands
for Brackets, E for Exponentiation, D for Division, M for Multiplication, A for Addition
and S for Subtraction.
You can also use cell addresses to perform calculation in the following way:
Notice that when the cell C1 is selected, Formula bar shows the formula you just typed. You can also
calculate the sum of adjacent cells by pressing the Alt+= keys together after selecting the cells.
What appears in the cell is the result.
What appears in the formula bar is the value, which is a formula in this case.
The elements of a formula are:
References: A cell or a range of cells that you want to use in your calculation.
Operators: Symbols (+, -, *, /, ^, $, %, etc.) that specify the calculations to be performed.
Constants: Numbers or text values that do not change.
ORDER OF OPERATION
While performing calculations using a formula, Excel follows certain rules of precedence:
Excel calculates expressions within parentheses ‘(‘ , ’)’ first.
Excel calculates multiplication and division before addition and subtraction.
Excel calculates consecutive operators with the same level of precedence from left to right.
For example, the formula = 10 + 10 * 2 gives a result of 30 as Excel multiplies 10 by 2 and then adds 10.
However, the formula =(10 + 10)*2 produces a result of 40. This is because Excel calculates the
expression (10 + 10) within the parentheses first and then multiplies by 2.
If you are unsure of the order in which Excel calculates, use parentheses even if the parentheses aren’t
necessary. Parentheses also make your formulas easier to read.
DIFFERENT WAYS TO ENTER FORMULAS
There are mainly two ways to enter a formula in a worksheet:
Typing the formula directly in the Cell: In this way, formula is directly typed in the cell after typing
an equal to sign. After entering the formula in the cell, press the Enter key. When the Enter key is
pressed, the result of formula appears in the cell.
