Question

Explain why
0 divided by 7 =0, but
7 divided by 0 does not exsist

Answer 1

`(0)/(7) = 0`
`[(0)/(x) =0 ]`

0 divided by any number will equal to 0 and has meaning.

`(7)/(0) =0`.
`[ (x)/(0) = 0 ]`

the expression has no meaning. any number divided by 0 is undefined.

`(0)/(7)` = 0 [ apply
`(0)/(a)=0` rule ] as 0 divided by any number will equal to 0 and has meaning.

`(7)/(0)` = undefined. [ apply
`(a)/(0)\:\mathr` = undefined rule ] as the expression has no meaning. any number divided by 0 is undefined.
