## Adding formula column
![Formula](https://user-images.githubusercontent.com/86527202/144246227-42c44df6-7e3e-4b2c-9bb9-a3c213bcad20.png)
### 1. Click on '+' (Add column)
### 2. Populate column Name
### 3. Select column Type as 'Formula'
### 4. Insert required formula
- Can use column names in equation
- Can use explicit numberical values/ strings as needed
- Table below lists supported formula & associated syntax
- Nested formula (formula equation referring to another formula column) are not supported
### 5. Click on 'Save'
