One of the best tips for Excel that I’ve ever been given is “if you can automate it…set up a formula”.
There is nothing more frustrating than trying to figure out calculations if you don’t understand the rules – Excel can do the number crunching, which means I can focus on adding the data and analysing it. It reduces errors too, as once the formula is set up, and the format for the answer cell is correct, the results are updated automatically.
Terminology is key to understanding how to set up formulas. This used to be the section that induced mild panic for me, but knowing the language of formulas means I can follow the instructions from Microsoft Help, and know which of the ready made formulas can give me the results I’m after.
Formula operators apply the calculations in your worksheet. These include the arithmetic operators of addition, subtraction, multiplication and division. You can also add percent % and caret
To apply these operators you need to know the symbols to use: Brackets ( ), addition +, subtraction -, multiplication *, Division /, and Exponent ^.
These are used in formulas to compare two values. The comparison operators are equals (=), greater than (>), less than (<), greater than or equal to (>=) and not equal to (<>)
This is used to concatenate (join) two values to give one continuous value. The ampersand (&) is used to join two values to give one value.
Reference operators are used to combine ranges of cells between two reference points. The colon (:) gives one reference to all cells between two references (for example when adding a column you have the starting reference point and end reference point, B2:B12. The comma (,) combines a number of references into one. and the use of space gives one reference to cells, common to two references.
The order of calculations
To set up your formulas, you need to know about the order of calculations. You may have heard the acronyms Bedmas or Bodmas – this is a useful way to remember which operator comes first
- B stands for Brackets
- E stands for Exponents, or O for Order
- D stands for Division
- M stands for Multiplication
- A stands for Addition
- S stands for Subtraction
Excel formulas can take your work to a higher level, improve your data analysis and speed up decision-making.
