The question immediately arises of the precedence of operators: which
operators are evaluated first and which last? There are many rules about
this topic, which your compiler will define completely, but I would
suggest that you don’t worry about it at this point. Instead, use lots of
parentheses to group variables, constants, and operators in a way
meaningful to you. Parentheses always have the highest priority and will
remove any question of which operations will be done first in any
particular statements.
