-6

Step-by-step explanation:

1. Treat the problem like a subtraction problem because -2.5 + (-3.5) can be rewritten as -2.5-3.5

2. When adding or subtracting negative numbers, keep these rules in mind:

Same signs add and keep.

Different signs subtract.

Keep the sign of the higher number.

-2.5 -3.5 have the same sign, so add them up and keep the sign.

And you do get -6.
