Question

UpStudy AI · Accepted Answer

**Step 1: Evaluate $$ -35 - 45 $$**

Subtracting a positive number from a negative number is equivalent to adding two negative numbers. Thus:

$$
-35 - 45 = -35 + (-45)
$$

Now, add the two negative numbers:

$$
-35 + (-45) = -(35 + 45) = -80
$$

**Step 2: Evaluate $$ 9 - (-3) $$**

Subtracting a negative number is equivalent to addition:

$$
9 - (-3) = 9 + 3
$$

Now, add the two numbers:

$$
9 + 3 = 12
$$

**Final Answers:**

$$
-35-45=-80 \quad \text{and} \quad 9-(-3)=12
$$
$$ -35 - 45 = -80 \quad \text{and} \quad 9 - (-3) = 12 $$
