Answer 2

To add (-3) and (-17), we can use the commutative property of addition, which states that changing the order of the addends does not change the sum.

So, we can write (-3) + (-17) as (-17) + (-3).

Now, we can add the numbers without their signs:

17 + 3 = 20.

The sum without the signs is 20.

Since both numbers have negative signs, the final answer will also have a negative sign.

Therefore, (-3) + (-17) = -20.
