Operations are done row-wise. Minitab conducts operations in the following order: subscripts, functions and column operations, exponentiation, "Not", multiplication and division, addition and subtraction, comparison operations, "And", and "Or". Operations of equal order are performed from left to right.
You can override the default precedence by using parentheses. Minitab runs expressions within ( ) first.
Expressions may include columns, stored constants, numbers, and text, but not matrices.
Use an asterisk (*) to represent a string of one or more characters. Use a question mark (?) to represent only one character.
To reference the "*" or "?" character in a text string, use the tilda (~) before the symbol.
If the last operation evaluated is a date/time function, such as NOW or WHEN, Minitab stores the result as a date/time value. For example, the result of DATE(TODAY() - 30) is a date value, because the last operation evaluated is DATE, a date/time function.
In Minitab, as with most spreadsheets, if you operate on a date/time variable with a number; for example, NOW() + 30, Minitab assumes the number is in units of days.
