(500 easy points) how to write a Jscript calculator

@AnnieMod
I do understand that that shouln't be allowed.
But how do I know that it's an Homework question?

RNBY

I will try to give attention to that.
I just didn't know,
(And even couldn't remember reading it in the rules)
But we learn from mistakes.
I looked at his other questions but didn't see any of them deleted.
Maybe you should give a good look to his other questions.
Or even ask him himself where this is for.

ok, iI fully understand it,
thanks for pointing it out to me.
I will be more carefull the next time.

Okay, I am sorry to have created this confusion. I am posting the original code just so there are no discrepancies. I am trying to learn web development, and we have a curriculum through our corporate training program. So I guess this would be academic tutoring, but the corporate training program is not accredited by any means.

Again I am not a high school student posting homework, but my HTML is at the level of a 6th grader.

Sorry for the confusion.

Thanks for informing us on that.
Sorry for any wrong accusations.
