#3B - 4#


According to the order of operations, multiplication happens before subtraction (unless specified otherwise). So, first we multiply #B# by #3#, then subtract the #4# afterward.

Note that a constant (a numerical number) multiplied by a variable (a letter or symbol) can be represented by writing them side by side with no operator in between.
