Memorising as many times tables as possible is a good idea if you want to do well in maths, and KS3 Maths is no different. Usually, people learn the times tables up to 12 but we thought you'd like a bit more of a challenge. So we're going to test your times table knowledge all the way up to the 20 times table. In this quiz we look at the 15 times table.
165, 225 and 285 are multiples of 15 and so they are all found in the 15 times table. 15 is a triangular number and one which we come across quite often. Each player has 15 counters at the start of a game of backgammon and there are 15 red balls in a game of snooker. 15 is also an odd number. The Roman natural historian and philosopher, Pliny the Elder, said "Why do we believe that in all matters the odd numbers are more powerful?"
It's all about practise when it comes to memorising the times tables. Have a go at this quiz and see how well you know the 15 times table.
