Move the '2' method:

Think of the 1st two figures in the 3-figure bearing as separate numbers, one of which will be larger than the other

eg 150 deg ==> 1 ---- 5 ----- 0

ie the '1' and the '5' are the figures to be considered.


Consider the larger number to be composed of '2' plus some other number, in this case '2' + '3'.

Mentally 'move' the 2 to the other figure - the '1' - and add them.

eg 150 ==> 1, 2+3, 0 ==> 1+2, 3, 0 ==> 330


There is an exception. When the 1st figure is a '3' then you would automatically treat that figure as the one with the '2' in it ie 1+2

I know it sounds long winded when written out. It's a damn sight easier to explain in person with a white board!

More examples


040 ==> 0, 2+2, 0 ==> 0+2, 2, 0 ==> 220

095 ==> 0, 2+7, 5 ==> 0+2, 7, 5 ==> 275

180 ==> 1, 2+6, 0, 0 ==> 1+2 ,6, 0, ==> 360

348 ==> 1+2, 4, 8, ==> 1, 2+4, 8 ==>168
