Answer 2

It seems like you've provided a mathematical expression:

B + (7,8 – b – 1,9)

However, the expression is a bit unclear due to the use of commas. I'm assuming you want to simplify or evaluate the expression. If that's the case, please clarify the intended mathematical operation and the values of 'B' and 'b'.

Here are a couple of interpretations based on your expression:

1. If you're looking to simplify the expression by performing arithmetic operations, please provide the values of 'B' and 'b'.

2. If you meant for the numbers to be treated as decimal numbers, then the expression might look like this:

   B + (7.8 - b - 1.9)

   Again, please provide the values of 'B' and 'b' so I can assist you further.

3. If you meant for the numbers to be treated as separate integers, it would look like this:

   B + (7, 8 - b - 1, 9)

   However, it's not common to use commas in this way in mathematical expressions. If you meant something else, please provide more context or clarification.
