Answer:
-5
Explanation:
This can be added/subtracted simply. Just take into account the negative symbols.
We'll start with the first two numbers:
(-3)+(5)
We have a negative number, -3. We'll add 5 positive numbers.
-3, -2, -1, 0, 1, 2
(-3)+(5) = 2.
Now that we have this number, we add it to the final number.
(2)+(-7)
We may be adding, but we are adding a negative number, so we are actually subtracting. We adding 7 negative points to the number 2.
2, 1, 0, -1, -2, -3, -4, -5.
Thus, our final answer is -5.
