1. ## Question

Hello,

Could anyone give me difficult various problems that will end in the result of 111. Why 111? I'm trying to prove a relationship between numbers for my class regarding Algebra.

Thanks.

How about solve for $\displaystyle x$ where $\displaystyle x -\sin \frac{\pi}{2} = 0.001\times 10^5$

but here x=101.

To the OP I would ask, what level are your students at? What relationship do you want to prove?

I think this thread is better in the Math Puzzles section.

Here's a question for you. Find the largest integer $\displaystyle n$ such that $\displaystyle 450!$ is divisible by $\displaystyle 10^n.$

$\displaystyle 3 \times 37$

$\displaystyle 1 +10 + 100 \:=\:\dfrac{10^3 -1}{10-1}$

$\displaystyle (10 + i\sqrt{11})(10 - i\sqrt{11})$
