Lesson 11

Reciprocal & Multiplicative Inverse-Order of Operations –Identifying Multiplication &

Addition

If one fraction is the inverted form of another fraction, each of the fractions is said to be the RECIPROCAL of the other fraction. For example:3/2 is the reciprocal of 2/3-4/11 is the reciprocal of -11/4 1/4 is the reciprocal of 4-5 is the reciprocal of -1/51/0 is MEANINGLESS and therefore ZERO is the ONLY real number which DOES NOT have a RECIPROCAL.If a number is multiplied by its reciprocal the PRODUCT is the number 1.

Definition of Reciprocal or Multiplicative Inverse

For any nonzero real number a, the RECIPROCAL, or MULTIPLICATIVE INVERSE,

of the number is 1/a.ORDER OF OPERATIONS
