To add (-3) and (-17), you can use the properties of operations. When adding negative numbers, you can think of it as subtracting the absolute values of the numbers and keeping the negative sign of the larger number.
In this case, the absolute value of -3 is 3, and the absolute value of -17 is 17.
We subtract the absolute values: 17 - 3 = 14
Since -17 is the larger number and it is negative, the answer is -14.
So, the correct answer is negative 14.
To add negative numbers, you can use the properties of operations. The property that applies here is the additive inverse property. According to this property, the sum of a number and its additive inverse is always zero.
In this case, you want to add (-3) and (-17). To find the sum, you can rewrite the problem as (-3) + (-17). By using the additive inverse property, you can change this expression to (-3) + (+17).
Now, you can add the numbers together: (-3) + (+17) = (+14).
Therefore, the correct answer is 14.
