### Math Wizz used Probability to Beat Lotto

December31

Romanian economist Stefan Mandel was struggling to make ends meet. So he came up with an unlikely solution — winning the lottery. But while most people who dream of scooping the jackpot rely on dumb luck, Mandel had other ideas. Mandel spent his spare time poring over probability papers penned by mathematician Leonardo Fibonacci — […]

### Fibonacci’s Rabbits – breeding like…rabbits

December14

The original problem that Fibonacci investigated (in the year 1202) was about how fast rabbits could breed in ideal circumstances. Suppose a newly-born pair of rabbits, one male, one female, are put in a field. Rabbits are able to mate at the age of one month so that at the end of its second month […]

### I want to know why Maths works, not just how!

June8

ScienceDaily (Apr. 10, 2009) — research from Vanderbilt University has found students benefit more from being taught the concepts behind math problems rather than the exact procedures to solve the problems. The findings offer teachers new insights on how best to shape math instruction to have the greatest impact on student learning. Full article here!

### Using Fibonacci to Easily Expand

April9

Now, you might well ask, how can we use Fibonacci to make our Algebra life easier. Well, here is a really good use which you can use in senior grades (note the pattern of coefficients in the expansion in red – same as the Fibonacci numbers to the left): answer to the 4th expansion will […]

### Fibonacci Again

April9

As the recent post on Mathematics and Art indicated, there is a very close relationship between the two, and this was discovered by Fibonacci. The picture on the right is from his statue in the town of Pisa, Italy. These were interesting (and challenging) times in the Middle Ages. As one education website mentions; “By the end […]

### Mathematics and Art – III

April4

The Golden Ratio, or Golden Number, has been well known for centuries as a pleasing balance of length to height and is seen in nature. Therefore, it is commonly used in Architecture and Art. For mathematicians, this ratio is called Phi: Phi (Φ and φ, pronounced [fī]) is a Greek letter. In mathematics it is used […]

The graph on the left (Coronavirus) is for a time period of 30 days, while the one on the right (SARS) is for 8 months! Very poor graphical comparison and hardly relevant, unless it is attempting to downplay the seriousness of the coronavirus?

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
