Formulas let you transform and combine existing fields into a new Formula field. For example, you can:
 Concatenate
First name
andLast name
fields into aFull name
Formula field.  Multiply
Price
andUnits
field to get the result in theRevenue
Formula field.
The field will show only in your Stacker app, and won't show up in your Airtable base or Google Sheets.
Create a formula field
 Go to Manage Fields and data

Fields in formulas
To use a field in a formula, the field needs to be in the table where you're creating the formula field. It also needs to be one of the following data types:
 Text
 Long Text
 Number
 Checkbox
 URL
 Single Select Dropdown
 Percentage
 Currency
 Rich Text
 Date
 Date and Time
 Multiple Select Dropdown
To use a field in a formula, you will need to wrap it in curly brackets. For example, {Price}. If you type in the opening curly bracket, we will suggest all available fields.
List of formulas
Functions work with any valid field data types, while operators work only on number fields. If you use an operator for a nonnumber field, we will try to convert it into a number. If we can't, you'll see an error message.
SUM
Returns the sum of two or more numbers.
Example:
SUM({Sold},{Not sold})
or
{Sold} + {Not sold}
SUBTRACT
Returns the difference of two numbers.
Example:
{Total stock}  {Sold stock}
MULTIPLY
Returns the product of two numbers.
Example:
{Sold} * {Price}
DIVIDE
Returns one number divided by another.
Example:
{Total sold} / {Price}
AVERAGE
Returns the average of the values in two or more fields.
Example:
AVERAGE({Sold},{Not sold})
NOT EQUAL TO
Check if one value is not equal to another.
Example:
1!=2 =>True
(represented as a checked checkbox)
EQUAL TO
Compare if one value is equal to another value.
Example:
1=1 =>True
(represented as an empty checkbox)
GREATER THAN
Compare if one value is greater than another value.
Example:
