    A mathematician and an engineer were stood on one side of a room, with a beautiful woman on the other. They were told that with each step they could cover half the remaining distance between themself and the woman. The mathematician worked out that he would never reach her, the engineer that after three steps he would be close enough for all practical purposes.

    In the mathematics joke theme...

    Did you hear about the mathematician who had constipation? He worked it out with a pencil

    The square root of 16 is 4 (4 x 4) and the third root of 8 is 2 (2 x 2 x 2). Four plus two is six. Doable for a 17-year old who has been taking mathematics, yes?"

    I would like to think that when I was a 17 year old who had been taking mathematics I would have given a more complete answer to this question.
    As a maths teacher I find the concept that numbers are racist bonkers. However I do think it’s important to teach that the history of maths/science isn’t a purely White Western male discipline. It’s important for children to see examples of themselves in what they learn. Part of the curriculum now includes “cultural capital” and it’s provides a good time to fit in that Arabic cultures/Asian cultures/women etc can do maths as well. And that different cultures think and represent number differently.

    A cool representation of that is Japanese multiplication https://m.youtube.com/watch?v=gngvWShRgX4

    When/if the police stop and question/search coloured people is it racist, stereotypical or doing there job.

    I do agree everyone could do more BUT so could the gangs with knives and drug gangs.

    Tough call.

    There's something very dodgy about this. None of the digits multiplied is bigger than 3, so the multiplication of two of these digits only ever yields a one-digit result (i.e. between 0 and 9. Looks like the method wouldn't work for, say, 58 x 46.

    That's what I thought at first, but there is one example where there is a carry.
