Question

1. 3 + (-7) + (-8)

Explanation:

Step1: Simplify the addition of negative numbers

First, we handle the addition of the negative terms. Recall that adding a negative number is the same as subtracting its positive counterpart. So, \(3 + (-7) + (-8)\) can be rewritten as \(3 - 7 - 8\).

Step2: Perform the first subtraction

Calculate \(3 - 7\). \(3 - 7 = -4\).

Step3: Perform the second subtraction

Now, take the result from Step 2 and subtract 8: \(-4 - 8 = -12\).

Answer:

\(-12\)
