Pi Day comes first in NZ

March14

Yes, it’s true – Pi Day does come early in New Zealand, and a day later for our students in the USA. Other than being able to find your birthday in Pi, why is Pi important enough to deserve a day of its own — and a search engine to draw attention to it? Click […]

Wacky Pi Day Activities…

March14

Wacky Pi Day activities, just in from Time.com: • In New York City, hundreds are expected to gather around a park fountain at 9:26 a.m. and with glow sticks in hand at 9:26 p.m. (to represent pi as 3.1415926) in an event organized by the National Museum of Mathematics (MoMath). • Lovebirds can get married […]

Pi Day Revisited

December1

Yes, today is NOT Pi Day – well, not officially. After all, every day is Pi Day since every day Pi is being used to solve both simple and complex problems, many times without anyone realizing it. Yes, Pi might just have to be the most exciting irrational number on the planet! What do we mean […]

Pi Day, Oz Style

March14

Yes, we were ahead of our lagging mathematicians in other classrooms today – with an early Pi DAY. March 14 (3.14) is a day ahead of our American counterparts and staff were delighted to receive small jam and lemon tarts to celebrate this auspicious day in the Mathematics calendar! Would love to see photos from […]

Pi Day is getting closer!

March3

Yes, we are again (see the last Pi Post) heading towards Pi Day (March 14 or 3/14 in the USA). Of course, in Australia and New Zealand we are able to celebrate a day earlier (on 14/03) than our North American mathematicians! We wonder whether Google will produce a unique Pi Day logo?

Gosh…we missed Pi Day!

March25

How did it happen? We missed Pi Day – 03/14 or 3.14 aka March 14th, which is the day that we all (except us on this blog) celebrate this famous value in Mathematics. Check out this video from CNN; Click on the image to play the video

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)?]
