School Math Classic problems submitted by students in Elementary
Math classes. You remember grade
school math. Right? If not, after trying the solution yourself,
an animated solution is presented so you won't be embarrassed. 

Classic problem of Camels and Prime Numbers. Specially designed to make your friends, whom you try it on, feel stupid for not getting the solution on their own. 

Classic problem with Rates. Anyone in business, construction or manufacturing is supposed
to be able to compute simple rate problems since almost everything has a
"rate"associated with it.
At least they are supposed to be able to compute such problems, until
this one. 

A seeming elementary problem that demonstrates that
even simple problems often do not fit the "plug in" equations you
learned in high school or college and "inspiration" and
"serendipity" are often required. 

Telling Time.
Most of us learned to tell time on a clock by the Third or Fourth
Grade. This teaser will show your
friends that they don't always know "what time IT is." 

Probability.
While Algebra is hard for most folks, "now probability theory,
whew, that's another matter!"
Yet knowing, and understanding, probabilities can be many more times
useful than Algebra  it can even save your life. 

With Math You Win.
Many games we play are highly mathematical and when you "know the
math" you can increase your edge in the game. With this one, understanding the math means you ALWAYS WIN. 

The Power of Math.
Math is extremely powerful when combined with exponents, or powers of
10, called Scientific Notation. With
this it seems you can almost hold the Universe in your hands.
