27th June - 3rd July
Three challenges to set you thinking: How many can you solve...........?

Your challenge is to move 3 matches to show 2 squares.

No. 2: "Nenek’s age"

Mamat asked his nenek how old she was. Rather than giving him a straight answer, she replied: "I have 6 children, and there are 4 years between each one and the next. I had my first child (Pak Long Husin) when I was 19. Now the youngest one (Mak Su Jamilah) is 19 herself. That's all I'm telling you!". How old is Mamat's nenek?

No. 3: "Peas Galore"

At a school fete people were asked to guess how many peas there were in a jar. No one guessed correctly, but the nearest guesses were 163, 169, 178 and 182. One of the numbers was one out, one was three out, one was ten out and the other sixteen out.
How many peas were there in the jar?
