(*Display Figure 3.)*

Using this approach, the result of evaluating the arithmetic expression in the first statement in Figure 3 is 7*3 or 21.

The result of evaluating the arithmetic expression in the second statement is 5+6 or 11.

Parentheses are always cleared out beginning with the inner-most parentheses and working outward to the outer-most pair of parentheses.
