How to subtract using partitioning

To partition a number using place values is to split it into tens and units etc. as appropriate, to use partitioning for subtraction you split the number being subtracted into tens and units then subtract the units from the given number to create a new number, then you subtract the tens from the new number to get the final answer.


53 - 15

subtract units    53 - 5 = 48

subtract tens    48 - 10 = 38

answer = 38
