Explanation
-89 could represent the idea someone is 89 dollars in debt.
Adding on -83 means they take on 83 more dollars of debt.
The total debt is 89+83 = 172 dollars
-89 + (-83) = -172 to show the result is negative.
Adding any two negatives will make the result negative.
-------------
Another way to think about it.
You are 89 meters below the surface of the ocean. That is represented by the number -89. Draw out a vertical number line.
Then move 83 units down to arrive at -172. Refer to the scratch work in the previous section.
This is one visual way to represent -89 + (-83) = -172
-------------
Note: adding a negative is the same as subtracting. Therefore, -89 + (-83) = -172 is the same as -89 - 83 = -172
The sum of -89 and -83 is negative.
Here's how we can reach that answer:
Both -89 and -83 are negative numbers.
When adding two negative numbers, the result is also negative.
Adding the two numbers together, we get: -89 + (-83) = -172.
Therefore, the sum of -89 and -83 is negative (-172).
I hope my answer will help you understand !
