Hi guys in this blog I will be showing you my maths follow up our goal was in maths Use a broad range of strategies to solve addition and subtraction problems with whole numbers and decimals.
here is how you do rounding and compensating
1245+3889 +1= 3890. 1245 + 3890= 5135-1 because you plus one to make it easier to work out to then you have to subtract that in number so 5135-1= 5134 there is your answer.
do you know how to do rounding and compensating? if so can you do reversibility?
