Requires you to understand that the number such as 385 is in fact three 100’s eight 10’s and five 1’s.

Or           300 + 80 + 5

And this place value system is called the decimal system.

Remember this is better than adding pounds shillings and pence.

NOTE:

d = pennies = 12 pennies in a shilling

S = shillings = 20 shillings in a pound

£ = Pound = 240 pence (12xx20=240)

and 8d+7d+10d=25d or 2 shillings and 1d

and 4S+5S+3S and 2S carried over is 14 shillings
