Namaste everyone,
Why does “int x = 200/0;”
gives an error but
int x = 200/20\*0; gives the value as 0.?
Thanks.

Because `200/20*0` is `(200/20)*0`, not `200/(20*0)`.

Hello @prathmesh,
A search for:

will reveal the answer to your question.
The Oracle Java documentation:

> This beginner Java tutorial describes fundamentals of programming in the Java programming language
> When writing compound expressions, be explicit and indicate with parentheses which operators should be evaluated first. This practice makes code easier to read and to maintain.
