Because you're subtracting a larger number from a smaller number. For example, 5-2 = 3, but 2-5 = -3.
Thanks a million richard, does that rule count for all subtractions on any type of number and not just decimals?Quote:

Doesn't matter if that number is decimal, fraction, integer, etc.Quote:

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.
The traditional way to do subtraction is to put the larger number (larger = larger absolute value) on top.Quote:
