Answer: 5
Explanation:
To evaluate the expression 5+(-11)-(-11), we must follow the order of operations, which dictates the order in which arithmetic operations should be performed.
The first operation to be performed is the one inside the parentheses, so we start by evaluating 5+(-11) = -6.
Next, we must perform the subtraction operation, which gives us -6-(-11) = -6+11 = 5.
Therefore, the final result of the expression 5+(-11)-(-11) is 5.
It is important to note that the negative sign in front of a number is called a "unary minus" and it indicates that the number is negative. In contrast, the minus sign used between two numbers indicates that they should be subtracted from each other. In this case, the unary minus in front of the 11 indicates that it is a negative number, while the minus sign between the two 11's indicates that they should be subtracted from each other.
