If you are dreading this chapter because you don’t like math—relax, C++ does all your math for you! It is a misconception that you have to be good at math to understand how to program computers. In fact, programming practice assumes the opposite is true! Your computer is your “slave,” to follow your instructions, and to do all the calculations for you. This chapter explains how C++ computes by introducing you to ♦ Primary math operators ♦ Order of operator precedence ♦ Assignment statements ♦ Mixed data type calculations ♦ Type casting

A C++ math operator is a symbol used for adding, subtracting,multiplying, dividing, and other operations. C++ operators are not always mathematical in nature, but many are. Table 8.1 lists these operator symbols and their primary meanings.

Most of these operators work in the familiar way you expect them to. Multiplication, addition, and subtraction produce the same results (and the division operator usually does) as those produced with a calculator. Table 8.2 illustrates four of these simple operators.
