*Sign up*Arithmetic Operations
Calculation operators:
+ - * / ^
Ordered left to right using operator precedence
May control using parenthesis to group operations
=(3+6)/2
will yield 4.5
= 3 + 6/2
will yield 6
Exponentials using caret ^
=3^2 will yield 9
May refer to other cells within the worksheet
If A2=5 & B2=4, then C2=A2*B2 will yield 20
C2 is known as a
dependent cell

Absolute vs Relative Addressing
Absolute cell referencing is used to keep a cell reference
constant; it uses “$” before row or column
Ex:
$B$20 is absolute & B20 is relative
May mix references, i.e. B$20, where the column
reference changes when you copy this cell to another
because it is relative.
The row reference does not change
because it is absolute.

*Sign up*Absolute vs Relative Addressing
May use formulas with absolute cell references
Ex:
=A4*(1 + $C$3)
Where:
A4 is relative and $C$3 is absolute
Most useful for columns or rows of data, where the same
operation must be performed multiple times
