Answer 2

It looks like you are providing some mathematical expressions where you're using parentheses and symbols to indicate operations. Let me interpret and simplify each expression for you:

1. *(7,6) = -7,6 This expression is a bit unclear because the comma seems to act as a separator. However, assuming you meant multiplication, it would be: *(7,6) = 7 * 6 = 42

2. +(*99) = -99 This expression is also not clear, but assuming you meant addition and multiplication: +(*99) = + (9 * 9) = + 81 = 81

3. -(*56) = 56 Here, the symbol "-" followed by the multiplication seems to indicate negation: -(*56) = - (5 * 6) = - 30

If these interpretations are not what you intended, please provide further clarification, and I'll be glad to help!
