let's try to subtract nine point five seven minus eight point zero nine so try to pause this video and and figure this out first before we work through it together all right well let's just rewrite it let's rewrite it and when I rewrite it I like to line up the decimals this one it's a little intuitive we have eight point zero nine just like that and now we're ready to subtract and we want to subtract nine hundredths from seven hundredths well we don't have enough hundreds up here so let's move over here let's see if we can do some regrouping so we always have a higher number on top so over here we want to subtract zero zero tenths from five ten so we have enough tents over here so let's regroup so instead of five ten so I'm going to have four tenths and then I'm going to give that other tenth which is the same thing as ten hundreds over here so this becomes 1700s seventeen minus 9 is 8 4 minus 0 is 4 and then I have 9 minus 8 is 1 so this is going to be one point four eight
