    A couple of ways to do mental math is to break apart a number when multiplying for instance.............14 x 16 is the same as

    6 x 14=84
    +
    10 x 16=160

    Added together it 244

    The hard part about mental math is not the math itself but the remembering of numbers.

    Another quick trick is something like 59 x 59=?
    Round 59 up to 60.
    Take 60 x 60= 3600.  Subtract 2 x 60=120.  Add 1

    3600-120+1=3481
    39x39= 40x40-2(40)+1=1521

    Works like a charm.  There is not enough room to explain it but it will impress people that you are able to do numbers like this in your head.
