In general, mathematics disallows division by zero because the resulting answer is indeterminate. This is because division is not a fundamental operation in mathematics – it is defined as the inverse of multiplication.

If we say:

12 ÷ 4 = 3

we mean precisely the same as if we had said:

12 = 3 × 4

In other words, when we divide a number (called a *dividend*) * a* by some number

*we get a quotient*

**b**,*And this quotient*

**q**.**when multiplied by**

*q***gives us the number**

*b***.**

*a*** a** ÷

**=**

*b*

*q*or

** a** =

**×**

*q*

*b*Suppose ** b** is zero, then we have:

** a** ÷ 0 =

*q*or

** a** =

**× 0**

*q*This raises two problems:

(1) Any number multiplied by zero equals zero. Therefore,

** a** =

**× 0**

*q*can only be true if ** a** is equal to zero. [If

**is not equal to zero, let’s say**

*a***= 3. Then what number**

*a***times zero will give us**

*q***?]**

*a*(2) Even if ** a** = 0, then

**any**value of

**would satisfy the equation. Consequently the value of**

*q***is indeterminate.**
