Blog Post #83: Magical Duets!

Dear Readers,

My house number, 11, is a palindrome; so is 101 or 11 x 11 =121, but what about 11 x 101 x 11? The result 12221 is clearly palindromic, and it’s intended to let you know a very nice date for your diary: exactly three weeks from today, on 12.2.21, you’ll be able to enjoy on YouTube (at 19:30 Central European Time via http://www.musicamundischool.org and clicking on the banner there) a feast of fabulous, musical solo performances featuring many young talents of Musica Mundi School.

I have the pleasure of getting to teach Mathematics to every student who studies the subject at the school, and right now I have some delightful surprises starring Julija and Hoi Yuet.

Blog Post #81: Top of the Class, Nice Niklas!!

Dear Readers,

It is with great pleasure that I thank everyone who participated in the ‘Good Lives Global Prize Competition’ (see Blog Post #80).

Andy H. from Scotland was the very first person to reply with all the mathematical puzzles completely correct. Andy loves challenge puzzles so much that he simply wanted to enjoy them without being given a prize. So, in recognition of his excellent attitude, we have a bonus puzzle in Andy’s honour, down below.

Before then, I want to congratulate Quintijn van Heek (an A-Level Maths student of mine) and Krissy Teng (another great student at the beautiful Musica Mundi School in Waterloo, Belgium) for also solving all the mathematical puzzles. Well done, Quintijn and Krissy!

Blog Post #70: Back to the 70’s!

Dear Readers,

Today, my family has been busily and happily congratulating my son’s lovely girlfriend on turning 22. My personal message included the following sneaky fun surprise…

  • Pick any three-digit whole number which has three different digits from 1 to 9 (e.g. 236)
  • Write down all the two-digit whole numbers that can be made from your chosen three-digit number without repeating digits in the same number (e.g. 23, 26, 32, 36, 62, 63)
  • Add up all your two-digit numbers (e.g. 23+26+32+36+62+63=242)
  • Divide your total by the total of the digits in your chosen three-digit number (e.g. 242/(2+3+6)=242/11=22 for the birthday celebration today!)

Blog Post #48: Maths Enrichment and Fun from Cambridge

Dear Readers,

I am currently enjoying preparing a “Magic Maths” show packed with super-fun puzzles for my colleagues and students at Musica Mundi School, Waterloo. For inspirational sources of material, I use lots of good things from what is still beautiful in the world around us. Also, I reflect on all that I have read and learned from very fine books linked to the Cambridge Maths courses that my students are following.
