What is 6 x 18?

# The 18 Times Table

Committing to memory as many times tables as you can 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 18 times table.

36, 90 and 342 are all multiples of 18 and so they are found in the 18 times table. I hope you are having fun playing these quizzes. The mathematician, Richard J. Trudeau, said "Pure mathematics is the world's best game. It is more absorbing than chess, more of a gamble than poker, and lasts longer then Monopoly. It's free. It can be played anywhere - Archimedes did it in a bathtub."

So, think of practising your times tables as playing a game. Have fun learning and testing yourself on the 18 times table in this quiz.
