**Note!**

Enable the functions in one of the following ways:

- Press the "Formulae" button in the
**menu**, located in the very top of the Online Spreadsheet.
- Insert the relevant function manually right in the cell.

## Step-by-step guide for manual inserting of formulae:

- Start with the “=” sign.
- Insert the relevant function right after the “=” sign.
- Insert the formulae itself in round brackets "( )"
- Divide the values within a formula using the sign ","
- Press the
*"Enter"* button to get the result.

Thus, **the formula will have the following look:**

=min ( a1, c1)

## Examples of formulae & functions currently supported in 2D Takeoff:

=max (a1, b1, c1)

=min (a1, b1, c1)

=average (a1, b1, c1)

=count (a1, b1, c1)

=round (x, y), where **x** is the cell's name / the value itself / another function / a mathematical expression, and **y** is a number showing the amount of decimal places, **eg.** round (3467263.77, -3)

= a1-c1

= a1+b1+c1

= a1*b1

= a1/b1

## Helpful to remember:

- The function's value can be either a reference to a cell / range of cells, or the value itself (number / measurement).
- The formula is updated as soon as the cell used in this formula has been changed.
- There’s no difference whether you insert the value starting from a capital letter or not.
- Mathematical operations supported by Kreo can be used as the formula's argument. They are: addition, subtraction, multiplication, division, as well as the use of brackets.

## Most common mistakes done in inserting formulae:

The formula's result will be "*Invalid*" in the following cases:

- The argument contains the following values:
- 2 3 (a space is inserted)
- B3 0.25 (a space is inserted)
- 3..33333 (2 dots are inserted)
- Text is inserted.
**Exception:** the Count option!

- The argument is the link to the invalid cell.

- The rules for inserting formulae were violated, eg. the sign "=" has not been used at the beginning.

- The functions count/min/max/average/sum are used as the argument. In such a case you need to refer to the relevant cell with these calculations.

Note! Relative copying for formulae is also available in 2D Takeoff. You can easily copy a spreadsheet's cells together with all the data inside.
