Explain simply why 83 is the correct answer to: Kaiden is collecting cans of soup for the local soup kitchen. He collects 158 cans during his first week and 259 during the second week. If his goal is to collect 500 cans how many more cans of soup does he need to collect?. Explanation:
Kaiden collects 158 cans his first week and 259 cans during the second week. 158 + 259 = 417 cans of soup. Kaiden wants to collect a total of 500 cans, so he still needs 500 - 417 = 83 cans of soup.
