### 4. Insert required formula
- Can use column names in equation
- Can use explicit numberical values/ strings as needed
- You can reference column names in equation with `$`, e.g. `$column_name$`.
- You can use explicit numerical values/ strings as needed, e.g. `123` (numeric) or `"123"` (string).
- Table below lists supported formula & associated syntax
- Nested formula (formula equation referring to another formula column) are not supported
- Nested formula (formula equation referring to another formula column) is supported

| **IF** | `IF(expr, successCase, [failCase])` | `IF($Column$ > 1, Value1, Value2)` | successCase if `expr` evaluates to TRUE, elseCase otherwise |
| **SWITCH** | `SWITCH(expr, [pattern, value, ..., default])` | `SWITCH($Column$, 1, 'One', 2, 'Two', '--')` | Switch case value based on `expr` output |
| **AND** | `AND(expr1, [expr2,...])` | `AND($Column$ > 2, $Column$ < 10)` | TRUE if all `expr` evaluate to TRUE |
| **OR** | `OR(expr1, [expr2,...])` | `OR($Column$ > 2, $Column$ < 10)` | TRUE if at least one `expr` evaluates to TRUE |
Logical operators, along with Numerical operators can be used to build conditional `expressions`.
Examples:
```bash
IF(marksSecured > 80, "GradeA", "GradeB")
```
IF($marksSecured$ > 80, "GradeA", "GradeB")
```
```bash
SWITCH(quarterNumber,
```
SWITCH($quarterNumber$,
1, 'Jan-Mar',
2, 'Apr-Jun',
3, 'Jul-Sep',
4, 'Oct-Dec',
'INVALID'
)
```
