All the posts are free for everyone to enjoy, and today’s one is specially dedicated to Super Sigurd, the youngest of three children in a lovely Norwegian family with whom I often had the pleasure of doing fun Maths and Chess.
Sigurd is turning 11 today, and so we have lots of nice, sneaky surprises…!
It’s Wednesday, and W is the 23rd letter of the English alphabet. So, let’s start with the number 23.
Multiply by 19, because S (for Super Sigurd!) is the 19th letter of the alphabet.
Multiply by my favourite number, 3.
To crown this surprise, multiply by 11, Sigurd’s new age.
The result of 14421 is to wish Sigurd an unforgettable, happy birthday on 14.4.21=today !
Also, 14421 ÷ 11 = 1311,
like saying to Sigurd, “HAPPY BIRTHDAY (13 letters), 11 !”
Furthermore, it’s fun to note that, by changing just one digit, we have two ways of turning 1311 into a pretty palindrome…
Either change it to 1331, which equals 11 x 11 x 11
OR change it to 1111, which equals this blog post number times Sigurd’s new age: 101 x 11 = 1111.
It’s time now for Sigurd’s birthday chess puzzle…
Before revealing the chess solution, here’s a simple-looking yet rather enjoyable wee ‘word sum’ to increase the fun today…!
In ONE + ONE = TWO, each different letter stands for a different digit and each same letter stands for the same digit. The general digit options are 0-9, but neither O nor T can be 0 because ONE and TWO stand for proper three-digit numbers.
Your double fun challenge is to figure out the minimum possible value of ONE + ONE and also the maximum possible value of ONE + ONE if it equals TWO !
That’s a beautiful one + one for Sigurd’s 11th birthday, and yet it’s just a tiny illustration showing that, in Maths and everything created by God, there’s a limitless universe of surprises infinitely beyond our imagination still waiting to delight us for eternity in Heaven.

Sigurd’s ONE + ONE = TWO Sneaky Birthday Maths Brainteaser Solution
In this TWO-story,
the minimum possible value of ONE + ONE is 412
the maximum possible value of ONE + ONE is 964.
Very warm congratulations for finding either or both of those values.
To conclude this article, I would like to wish Sigurd and everyone a really wonderful, happy day now.
With kindest wishes as always,

P.S. Even when he was a grade 1 primary school student several years ago, young Sigurd already loved to do great mental calculations, and he understood mathematical concepts such as squaring, with 122 = 144 being one of his favourite examples, not only on 14/4 ! So, as an extra birthday treat, we have the following b☺nus brainteaser f☺r Sigurd…
Can you discover a future year in which
the total of the year + Sigurd’s age on his birthday in that year
would together make a Square Number ?
God-willing as always, it is my hope and intention to publish a solution at the time of the next blog post, or possibly even sooner.
SOLUTION to Super Sigurd’s Bonus Brainteaser (being posted on 14 May 2021)
In the year 2063, Sigurd will be 53. Then, 2063+53=2116, which is equal to 46 squared, since 46 x 46 = 2116.
