Answer 3

To solve the expression -3-(-6.9+5.8), we need to follow the order of operations, which is often represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, let's simplify the expression within the parentheses: -6.9 + 5.8 = -1.1.

Now we have: -3 - (-1.1).

To remove the negative sign from the second term, we can distribute the negative sign by changing the subtraction operation to addition with the opposite sign: -3 + 1.1.

Finally, we can subtract the two terms: -3 + 1.1 = -1.9.

Therefore, the result of the expression -3-(-6.9+5.8) is -1.9.
