operations, and properties of operations with real numbers; and 8. 4 The student will apply the order of operations to evaluate algebraic expressions for given replacement values of the variables. algebraic properties of real numbers pdf Page 1 of 2 1. 1 Real Numbers and Number Operations 3 Real Numbers and Number Operations USING THE REAL NUMBER LINE The numbers used most often in algebra are the real numbers. Some important subsets of the real numbers are listed below. Therefore, I say, real number properties, such as these algebraic properties, apply to operations on literal equations as well as onevariable equations. Teacher's Note: While reviewing the properties, I stress how all of the operations can be completed using addition or multiplication. The Identity Properties The numbers 0 and 1 have special properties. Multiplication of a number by 1 does not change the number, and addition of 0 to a number does not change the number. That is why 1 is called the multiplicative identity and 0 is called the additive identity. Identity Properties For any real number a, a 1 1 a a and a 0 0 a a.
