This doesn't really belong in Entertainment... As it isn't entertainment related nor a discussion. I'll send this to spam.

I can. Well, A little longer then five seconds, but still.
100x97= 9700
9700-97-97=9506.

I might be able to. But I starred at it for about 3 seconds, and decided to just wait on other people figuring it out.

Actually it's pretty simple, but I'm not gonna tell how just yet :P
I'll wait a little bit more until I reveal the solution.

Actually, there are plenty of people who can. There's an entire competition dedicated to stuff like this, at least in Texas. UIL Number Sense.
Anyways, 9506, and yes, less htan 5 seconds obviously. Lol the trick you're talking about is the number sense trick for multiplying two numbers close tobut under 100.
100 - 98 = 2
100 - 97 = 3
2 x 3 = 6
98 - 3 = 95
95 x 100 + 6 = 9506
One of the most basic tricks for Number Sense competition.

Looks like you got it, haha. Didn't expect such a fast answer, I was hoping that maybe it might take a day or two before someone found this out.
Nice job :D
