Why Can't You Divide By 0?
Why can't my denominator be equal to 0?
Summary
- If we divide by 0, then the answer is "undefined"
- We can't distribute 30 books among 0 people because there are no people to distribute to
- That is why 30/0 is undefined
- No number can be plugged in for 'x' to make 5 = 0 • x a true statement

Notes
-
- If we try to divide anything into nothing, or divide something into 0 parts, then it makes no sense
-
- If we try to divide anything into nothing, or divide something into 0 parts, then it makes no sense
- Since it makes no sense, we can't get an numerical answer from dividing by 0
-
- Does this question make sense? No, we cannot give 0 people anything
-
- 30 algebra books are being distributed (divided) evenly amongst 0 people
-
- So that's why our answer is "undefined"
-
-
- 'x' is a variable
- If 'x' can be anything, what can it be to make 0 • x = 5?
-
- No number works to make 0 • x = 5
-
- Dividing by 0 never leads to anything good!
