So proud to see my country’s Maths question represented here. It came out in the 2019 paper and received much attention - to the extent that our national daily covered it. Well done @Oxbitcoiner. You slayed it.
I think I am able to solve it, only because I have acquired an intuition for how such questions ought to be solved. Otherwise, I wouldn’t know how to tackle it.
The ability to spot patterns is important for our primary school Maths. Let me find similar questions from top schools’ prelim papers and post them here!
In Portugal, 11-12 year-olds are in the 6th or 7th grade of compulsory education. Compulsory education starts at 6 years old, but pre-primary education is optional. In 6th and 7th grade, math classes cover first-degree equations, rational numbers, and trigonometry. I think these exercises are interesting, but wouldn't this kind of problem be used to differentiate the more intelligent students in the Singaporean education system? I'm just curious, because it seems a bit advanced for a regular difficulty level.
