Problem: "A student must decide if the statement is always true: 'The sum of two odd numbers is even.'" They want a strategy. Which next step is best?
A
Multiply two odd numbers because that is more informative than adding.
B
Test one example and claim it proves 'always.'
C
Represent odd numbers as 2k + 1 and 2m + 1, add them, and simplify to show the result is even.
D
Assume it is false because odd numbers are unpredictable.
