### Math puts class into architecture

November19

The link between Mathematics and architecture goes back to ancient times. Pyramids and temples were some of the earliest examples of mathematical principles at work. Today, Mathematics continues to feature prominently in building design. Thanks to modern technology, architects can explore a variety of exciting design options based on complex mathematical formulae, allowing them to […]

### Topology – It has two sides but only one!

June21

Students may not have seen much about Topology while their heads are deep inside equations and trig functions. However, Mobius strips and Klein bottles are intriguing aspects of the area of Mathematics called Topology (literally, “the study of shapes”). Here is a Mobius Strip: The fun part of Mobius Strips is that students can make […]

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)?]
