Answer:
8. 95
Explanation:
The last equation 37 + 58 can be best solved by solving it vertically. Put 37 and 58 side to side vertically to add easier on a piece of paper. The first digit answer is 15, carry the 1 to the second digit and add it with 3 and 5. Your final answer should be 95.
The property that you should use is the Associative Property where you can switch the numbers to put the larger number on top and the smaller number on the bottom. No matter how it is changed, you should get the right answer.
