    How to see it

    Compare from the left, one column at a time. The first column that is different decides it. Nothing after that matters. Four millions is less than five millions. Done. All those nines never get a vote. The symbols: the mouth always opens towards the bigger number.

    A worked example

    Which of these is largest: 4,999,999, 5,100,000, 5,099,999, 5,010,000? Millions first. Four loses. Three of them have a 5, so they tie. Next column, hundred thousands. 1 beats 0. So 5,100,000 wins.

    The common mistake: judging by the later digits

    The trap is being pulled by big digits at the end. Look at all those nines, it feels enormous, and it is the smallest of the four.

    Try one

    Which is the largest? 999,999, 1,003,200, 1,030,200 or 1,030,199.

    1. A999,999
    2. B1,003,200
    3. C1,030,200
    4. D1,030,199
    Show the answer

    Right: C, 1,030,200

    It has the same start as D, but the hundreds digit beats it.
