The easiest would be to multiply from left to right starting with 5 x 300 which
= 1500 then 5 x 0 =0 and 5 x 6 =30 then add them up 1500 + 0 + 30 =1530 multiplying from left to right removes the need to carry or borrow making it much easier to do mentally.
Mental math is basically just giving an estimate of what the value will be, for example: 5x306= 5x3 and add 2 zeros will give you 1500 and the actual answer is 1530 so its kind of like rounding off to the nearest.

You can, if you wish.
