With numbers as well as with commands and text, when you don't have
a line number before a BASIC statement, you don't have to type RUN to
tell the computer to fohow the instruction; it's in IMMEDIATE, or DIRECT
MODE. Having a line number means the statement is part of a BASIC
program; it's in PROGRAM MODE. Either way is acceptable.
You can also include both a text statement in quotation marks and a
mathematical problem to be solved in a single PRINT statement in
immediate mode.

Your PlusM always performs calculations in a certain order. Problems
are solved from left to right; within that general rule, some types of
calculations are solved first. The order which your Plus/4 evaluates
expressions is called the order of precedence of operators.
