Answer:

-3.235

Step-by-step explanation:

First, let's start by removing the parentheses and simplifying the expression.

3.125 + - 3.9 - 2.46

Adding a negative number is the same as subtracting it, so we can remove the + sign.

3.125 - 3.9 - 2.46

From there, we can do simple subtraction and get:

-3.235
