A knowledge of the times tables will serve you well in all levels of mathematics, including KS3 Maths. Most of us learn the times tables up to 12 but we thought you'd like a bit more of a challenge so we're going all the way up to the 20 times table. This particular quiz will test how well you know the 16 times table.

64, 160 and 288 belong in the 16 times table - quite big numbers. Mathematician, Ronald Graham, said of large numbers "The trouble with integers is that we have examined only the very small ones. Maybe all the exciting stuff happens at really big numbers, ones we can't even begin to think about in any very definite way. Our brains have evolved to get us out of the rain, find where the berries are, and keep us from getting killed. Our brains did not evolve to help us grasp really large numbers or to look at things in a hundred thousand dimensions."

Practise is the best way to get to know your times tables. Have a go at this quiz and find out how well you get on with the 16 times table.

1.

What is 19 x 16

304

299

311

309

20 x 16 = 320 and 320 - 16 = 304

2.

What is 11 x 16

169

179

171

176

10 x 16 = 160 and 160 + 16 = 176

3.

What is 18 x 16

295

289

281

288

16 x 20 = 320 and 16 x 2 = 32 so 320 - 32 = 18 x 16

4.

What is 16 x 16

263

250

256

259

16 is the square root of 256

5.

What is 12 x 16

202

188

192

186

192 is the sum of ten consecutive primes (5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 + 31 + 37 = 192)

6.

What is 20 x 16

317

313

318

320

2 x 16 = 32 so 20 x 16 = 320

7.

What is 8 x 16

121

122

137

128

128 is 2^{7}

8.

What is 17 x 16

271

272

264

273

To work this one out subtract 3 x 16 (48) from 20 x 16 (320)

9.

What is 5 x 16

80

90

74

89

10 x 16 = 160 so halve this to find the answer

10.

What is 4 x 16

56

64

55

57

64 is the square of 8, the cube of 4, and the sixth power of 2
