1 Hav­ing heard a ra­dio pre­sen­ter sign off by say­ing “We’ve ran out of time” Pedan­ti­cus prowled the cor­ri­dors of the flat growl­ing; so I was care­ful to dis­tract him dur­ing a pro­gramme in which quite learned folk said not only “zoo-ol­ogy” but – O hor­ror hor­ro­rum! – “a bac­te­ria”. Why might hear­ing this have driven him over the edge?

2 On BBC Ra­dio 4 I men­tioned David Sing­mas­ter’s pen­cil bear­ing a trun­cat­able prime – a prime num­ber such that as you strike off dig­its one at a time from one end, the num­ber you are left with is also a prime. There are left-trun­cat­able primes, such as 9137 (as 9137, 137, 37 and 7 are all prime) and right-trun­cat­able primes like 7193 (7193, 719, 71 and 7 are all primes). Now do you sup­pose the prime on David’s pen­cil is left­trun­cat­able – or right-trun­cat­able?

3 If you mul­ti­ply 4321 by this 4-digit num­ber the an­swer you get ends in its re­verse, ie 1234. That’s to say: 4321 X **** = ****1234. What is the 4-digit num­ber? Twit­ter: @ChrisMasla­nka
