Sam plays a maths game. Each acorn is equal to two points. A leaf plus an acorn plus another acorn equals 10 points. How many points is one leaf equal to?
So we know an acorn is worth two points. We need to work out how much one leaf is worth. We know that the total of a leaf plus two acorns is 10. And we also know that each acorn is worth two points. So two plus two or two lots of two is four. Two acorns are worth four points.
What do we add to four to make 10? One, two, three, four, five, six. Six and four makes 10. So this tells us that one leaf is equal to six points. Six plus two plus two equals 10. One leaf is equal to six points.
