Why do they = -numbers?

Thanks!

Because you're subtracting a larger number from a smaller number. For example, 5-2 = 3, but 2-5 = -3.

I don't understand though, why can't you just do

56.19

24.65

Instead of doing it with the smallest number on top and having to have a - answer?

What is the difference between

4.56

- 5.53 = -0.97

5.67

- 4.42 = 1.25

I'm really confused, probably because I took a break from maths just then and I've came back with a puzzled mind. So why is one minis and one isnt? I know I just asked this but I don't see the difference between these two. - Jun 30th 2012, 01:50 PMrichard1234Re: Why are these decimal subtractions = minus numbers?
