How do you evaluate #3 * (-2) +6 -(-2) - 5#?
Make use of your operational sequence.
Let's remove the parentheses since they serve only to highlight the fact that the numbers are negative.
Since we don't have any exponents, multiplication is the next operation in the order of operations.
Now that division and multiplication have ceased, we can proceed to addition and subtraction, which are relatively simple.
The next negative is a double negative, which is added to whenever a negative number is subtracted.
That wasn't too difficult, after all.

To evaluate the expression, follow the order of operations (PEMDAS/BODMAS):
- Start with any operations inside parentheses or brackets: There is one set of parentheses: (-2).
- Evaluate any exponentiation: There are no exponents in this expression.
- Perform multiplication and division from left to right: There's multiplication (3 * (-2)).
- Then, perform addition and subtraction from left to right: Combine all the terms.
Now, let's evaluate:
3 * (-2) + 6 - (-2) - 5 = -6 + 6 - (-2) - 5 = 0 - (-2) - 5 = 2 - 5 = -3
So, the result is -3.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
