If you multiply ﬁve numbers, it does not matter what order you multiply them. If you add 0 to a real number or multiply a real number by 1, the result yields the original real number. Basic properties of real numbers are summarized in the following table. Because these properties are true for variables and algebraic expressions, these properties are often called the basic rules of algebra. qxd 8/7/12 10 5:34 PM Page 10 C H A P T E R 0 Prerequisites and Review P R O P E RTI E S O F R E AL N U M B E R S ( BAS I C R U LE S O F ALG E B R A ) MATH (LET a, b, NAME D ESCRIPTION AND c EACH BE ANY REAL NUMBER) E XAMPLE Commutative property of addition Two real numbers can be added in any order.

Decimals are approximated by either truncating or rounding. ■ ■ Truncating: Eliminate all values after a particular digit. Rounding: Look to the right of a particular digit. If the number is 5 or greater, increase the digit by 1; otherwise, leave it as is and eliminate all digits to the right.
