In a variety of daily life things for the typical student, you would be great to be successful at five things in a row or more. Shooting free throws, volleyball or tennis serving, five math steps in a row, 5 rugby passes in a row.  What is the chances of doing this if I am [...]

One of the three greatest mathematicians of all time (the other two being Newton and Gauss), Archimedes was the greatest mathematician and engineer from the ancient world. Here is a quick look at some of his accomplishments.  Please click on the name of the file below to see the pdf file.
Archimedes (287 BC to 212 [...]

Since rational expressions are merely fractions, (a weird looking fraction) they follow the rules of fractions. Since yesterday we learned about multiplying and dividing fractions, today we look at multiplying and dividing rational expressions. Please click on the name of the file below to see the pdf file.
Multiplying and Dividing Rational Expressions

Here are the 8th and the 9th (out of 10) rules of fractions, how to multiply and divide fractions. I have attempted to explain WHY the rules work as well as just HOW to do it.  To see, look at the comic strip below, and remember, if you want it larger, just click on it.
 

There are three types of fractions, in this post, Octa and Hexa discuss the different types and how you can change one to the other.  This will give you the 3rd and 4th rules (out of 10) about fractions. Click on the comic below if you want to enlarge it.
 

Sometimes it is useful to stretch one’s brain using logic and not mathematics. The Suduku puzzles are actually like this, as no math, but logic is necessary to solve them. The following puzzle will stump some English Language teachers, especially those who are punctuation promoters. We also include the answers to last week’s puzzles. Click [...]

I love mental math tricks. The video below is from my youtube collection (search minkusbc). It not only shows a really neat math trick, but it also shows you how it works and a cool use for learning how to square a binomial.

I love stories like this. Here you have some relatively obscure mathematical works, Euclid in about 300 BC, Fermat, in 1640 and Euler in 1736, who all discovered algorithms and theorems that were key to helping Ronald Rivest, Adi Shamir, and Leonard Adleman at MIT in 1977 to invent the RSA (the first letters of their [...]

We first met Eratosthenes when we used his Seive for finding prime numbers. Now, we really find out how bright, and advanced, he was, when we see how, by using simple observations and grade 8 geometry, he was able to measure the size of the Earth to within 1.8% of the correct answer, 2 450 [...]

The last two days we have seen the definition of a fraction and how to simplify a fraction and how to change the denominators of a fraction by multiplying the numerator and the denominator by the same thing. Now, we see a different type of a fraction, called a rational expression. The rules do NOT [...]
