This is no superhero P3 Maths, just copied from an ordinary text book...
I think what Primary school learn now has undergone radical changes, and also they seemed removed (or tuned down the importance of) some 'mechanical' things like practicing addition/subtraction in 3 or 4 digits. Maybe this is due to advance in computer and we no more needed to accurately practice algebra.
I don't know whether this is good or bad.

I see the examples like q's comment - that it's more of an IQ test on pattern recognition and math curiosities rather than hard core mathematics principles.
This little trick reminds me of our little poem:
3 guys walking 70 miles
5 horses riden by 21 people
7 brothers came home for 15 days
take out 105 is the answer

I personally think this is wrong. Sometimes things worthwhile doing are boring but necessary.
I have repeatedly told me kids the story of a full grown adult who couldn't add or estimate distance by converting km to mile. Unfortunately this kind of adult is more and more common these days.
Yes nowadays we have computers and calculators everywhere. But most of the smart and successful (business & job wise) people I know almost always have a good sense of numbers. They can visualize numbers in their heads. This is a good indicator of how well you can understand abstract concepts, and see the big pictures.
