Highlight Challenging Problems
The most challenging problem in Homework 5.4 is the last one, which asks students to prove that the sum of two odd numbers is even. This problem is difficult because it requires students to use indirect reasoning and to understand the definitions of even and odd numbers.To
solve this problem effectively, students can use the following strategies:
- First, they can define even and odd numbers. An even number is a number that is divisible by 2, while an odd number is a number that is not divisible by 2.
- Next, they can assume that the sum of two odd numbers is odd. This means that the sum is not divisible by 2.
- Then, they can show that this assumption leads to a contradiction. For example, they can show that if the sum of two odd numbers is odd, then one of the numbers must be even.
- Finally, they can conclude that their assumption was incorrect and that the sum of two odd numbers must be even.
