a(0) = 0

Because anything multiplied by NOTHING would still be nothing. You can't make something from nothing :)

It's like saying "I have 3 groups of zero people". Even if you had a hundred groups, there would be no one.

(0)a = 0

Same thing, but you could say:

"I have zero groups of 3 people"

It would just be like 0 + 0 + 0 = 0

---

0/a = 0

If you have zero cupcakes to divide among three people, in the end they'd get no cupcakes, because you had none in the first place!

a/0 = undefined

You can't divide anything by zero. It leads to a whole lot of contradiction.

Hope this helped =)

a(0)= 0 because it means a multiplied by 0 and anything multiplied by 0 is 0

(0)a= 0 ( same reason)

0/a = 0 anything divided by 0 is 0.

a/0 is undefined. nothing can be divided by 0
