Use properties of operations to add (−3) and (−17).
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.

To add (-3) and (-17) using properties of operations, follow these steps:
Step 1: Start with the given numbers, -3 and -17.
Step 2: To add negative numbers, we can think of it as subtracting the absolute values.
Step 3: Find the absolute values of -3 and -17. The absolute value of -3 is 3, and the absolute value of -17 is 17.
Step 4: Subtract the absolute values: 3 - 17 = -14.
Step 5: Since both numbers being added are negative, the sum is negative.
Therefore, (-3) + (-17) = -14.
To add (-3) and (-17) using properties of operations, you can make use of the commutative property of addition. According to the commutative property, changing the order of the numbers being added does not affect the result.
Here's a step-by-step explanation:
Step 1: Write down the numbers (-3) and (-17).
Step 2: Rearrange the numbers to change their order. Instead of adding (-3) and (-17), we can add (-17) and (-3).
Step 3: Add the numbers from left to right: (-17) + (-3).
Step 4: Add the absolute values of the numbers: 17 + 3 = 20.
Step 5: Determine the sign of the result. In this case, both numbers have a negative sign, so the result will also be negative.
Step 6: Write the sign and the sum from Step 4, which gives: -20.
Therefore, (-3) + (-17) is equal to -20.
