It looks like you've provided a list of expressions involving numbers. It seems you might be looking for assistance in evaluating these expressions. The expressions you've provided appear to be mixtures of decimals and operations. Let's evaluate each expression step by step:

a) 3.5 - 4.5: This expression simply involves subtracting 4.5 from 3.5: 3.5 - 4.5 = -1.0

b) 3.5 - (-4.5): Here, you're subtracting a negative number, which is the same as adding its positive counterpart: 3.5 + 4.5 = 8.0

B) -3.5 - 4.5: This expression involves subtracting 4.5 from -3.5: -3.5 - 4.5 = -8.0

r) -3.5 - (-4.5): Similar to the second expression, you're subtracting a negative number: -3.5 + 4.5 = 1.0

In summary: a) 3.5 - 4.5 = -1.0 b) 3.5 - (-4.5) = 8.0 B) -3.5 - 4.5 = -8.0 r) -3.5 - (-4.5) = 1.0
