Notice that when cell C1 is selected, the 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 formula, which is used to get the result.
The elements of a formula are:
References: A cell or a cell range 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
What if you could use Excel to track the books you’ve read and the books
you want to read? How would you rate them and what genres would you
include?
ORDER OF OPERATION
When 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. It then multiplies that result 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.
Reb t
The contents of a cell can be moved or copied to other cells.
Row height and column width can be changed.
You can specify a column width of 0 to 255 and a row height of 0 to 409.
Two or more cells can be merged into one cell.
AutoFill feature automatically fills a series of data in your worksheet.
Formulas in Excel begin with an equal (=) sign.
A cell or a cell range that you want to use in your calculation is called a reference.
Excel calculates consecutive operators with the same level of precedence from left to
right.
