You will need to do the reverse operation to get the answer quickest.
So 6.6 - 6.56 = ?. Think of it as 60 - 56. I think you know it is four.
So 6.6 - 6.56 = .04 Now the reverse is 6.56 + .04 = 6.6
So 6.6 - 6.56 = ?. Think of it as 60 - 56. I think you know it is four.
So 6.6 - 6.56 = .04 Now the reverse is 6.56 + .04 = 6.6
