#-0.45#

Explanation:

Simplify the expression by removing the parenthesis

#3.5-5.2--1.25#

Notice how we have two negative signs next to each other. This implies that we have two negatives that are multiplying. Thus, #-*-##=+#

So we rewrite the expression as

#3.5-5.2+1.25#

Evaluating this we get

#=-1.7+1.25#

#=-0.45#
