  1. Why is Division By Zero Undefined? Remember to Silence Your Cell Phone and Put It In Your Bag!

  2. If the divisor is zero and the dividend is not zero: If a  0, then a  0 is undefined b/c there is no number q such that q x 0 = a. q x 0 always equals 0. Examples: 1  0 = ? There is no number q such that q x 0 = 1. q x 0 = 0 (not 1). 2  0 = ? There is no number q such that q x 0 = 2. q x 0 = 0 (not 2). 3  0 = ? There is no number q such that q x 0 = 3. q x 0 = 0 (not 3).

  3. If both the divisor and dividend are zero: 0  0 is undefined b/c there is no unique number q such that q x 0 = 0. For any number q x 0 = 0. Examples: 0  0 = ? Can q = 1? 1 x 0 = 0 Can q = 2? 2 x 0 = 0 Can q = 3? 3 x 0 = 0

  4. Division by Zero is Undefined Because: • If a  0, then a  0 is undefined b/c there is no number q such that q x 0 = a. q x 0 always equals 0. • 0  0 is undefined b/c there is no unique number q such that q x 0 = 0. For any number q x 0 = 0.
