Operator - (Subtract)

left_value	(Required) Value to substract from
right_value	(Required) Value to substract

Examples

30 - 10 * 2	(None)	10

More information

Multiple operators can be used. The order of operation is the same as in mathematics:

content of parentheses is evaluated first
then exponents are evaluated, from right to left
then multiplication and division are evaluated, from left to right
the remaining operators are then applied from left to right

Reminders

A text containing digits is not handled as a number. To have an actual number:

use the @NUMBER_QUESTION to set the variable
write a numeric value directly in the code without quotes, ex: age >= 18
use a function which converts to a number: NUMBER(text_containing_numbers)
use a function which returns a number: FIND("world", "hello everybody")
