The - (subtract) operator takes two numbers, variables, or expressions and subtracts one from the other, thus returning the difference between them. The - operator appears lower in the order of operations than both [[TI-BASIC:Multiply|*]] and [[TI-BASIC:Divide|/]], so if those appear in an expression, they will be executed first. In addition, the [[TI-BASIC:Add|+]] operator has the same order of operations as -, so the calculator simply executes them left to right in the order that they appear.

= Error Conditions =

* '''[[TI-BASIC:Errors#syntax|ERR:SYNTAX]]''' is thrown if you try to use - (subtract) in place of [[TI-BASIC:Negative|‾]] (negative). Because they look very similar, it's easy to get this error; at the same time, it's an easy error to fix.
