I fear that when I take the national numeracy test on Wednesday, as I intend to do, my stress levels will be rising; I gave up maths at 15 after I took O-level. We should be shocked that one in two adults have the numeracy skills of an 11-year-old or younger—the figure is one in six for English—and that 11 million adults lack basic digital skills. We live in a rarefied atmosphere in this place, and some of us find it quite extraordinary to appreciate those facts. The test on Wednesday is a must for every Member of this House. I hope that they will join me in taking it, tweeting the picture, and making sure that everybody understands the need to be numerate.
