### Zero Has a New Hero

November16

London (2017): An ancient Indian manuscript, dating back to the third century, has revealed the oldest recorded use of ‘zero’ – pushing back one of the greatest breakthroughs in the history of mathematics back by over 500 years, Oxford scientists say. Bakhshali manuscript was found in 1881, buried in a field in what was then […]

### If maths is boring, what is the answer?

May17

Marcus du Sautoy, Professor of Mathematics at Wadham College, Oxford notes, “Who said maths was boring? A report published by Ofsted last month claimed that pupils are simply turned off by the parrot learning of formulas to solve quadratic equations and the mindless application of the rules of trigonometry. An obsession with teaching children solely […]

### Tiles and Tessellation Art Exhibition

January30

The art of fitting together mathematical shapes in repeating patterns is the basis of many fine designs and art work (unlike this one): In 2012 there was an excellent exhibition of mathematical art works. Click on this image below (“hyperbolic tiling”) to find out about these wonderful works and their author-artists: (Footnote: the first pic […]

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)?]
