# The 17 Times Table

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.

1. What is 15 x 17
10 x 17 = 170 and 5 x 17 = 85 so 170 + 85 = 15 x 17
2. What is 16 x 17
15 x 17 = 255 and 255 + 17 = 272
3. What is 2 x 17
34 has only 4 factors: 1, 2, 17 and 34
4. What is 18 x 17
2 x 17 = 34 so 20 x 17 = 340. Therefore, 340 - 34 = 18 x 17
5. What is 14 x 17
15 x 17 = 255 and 255 - 17 = 238
6. What is 6 x 17
102 has 8 factors: 1, 2, 3, 6, 17, 34, 51 and 102
7. What is 13 x 17
10 x 17 = 170 and 3 x 17 = 51 so 13 x 17 = 170 - 51
8. What is 20 x 17
2 x 17 = 34 so 20 x 17 = 340
9. What is 17 x 17
17 is the square root of 289
10. What is 4 x 17
5 x 17 = 85 and 85 - 17 = 68
