If you want to do well in maths it's a good idea to learn the times tables off by heart. Most people learn the times tables up to 12 but, for KS3 Maths, we thought you'd like a bit more of a challenge. That's why 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 17 times table.

34, 221 and 289 are answers found in the 17 times table. That's because they're all multiples of 17. Maths is of increasing importance in the modern world. As the mathematician and computer scientist, John Kemeny, said "The man ignorant of mathematics will be increasingly limited in his grasp of the main forces of civilisation."

If Kemeny is right then you'd better put your thinking cap on and improve your knowledge of the times tables! See how well you can do in this quiz all about the 17 times table.

2 x 17 = 34 so 20 x 17 = 340

5.

What is 16 x 17

262

270

272

271

15 x 17 = 255 and 255 + 17 = 272

6.

What is 14 x 17

235

244

228

238

15 x 17 = 255 and 255 - 17 = 238

7.

What is 15 x 17

252

255

248

265

10 x 17 = 170 and 5 x 17 = 85 so 170 + 85 = 15 x 17
