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

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.
