Which of these CANT give an integer divided by 10? A sum of 2 odd integers B integer less than 10 C sum of 3 consec. Integers D prod. Of 2 primes E odd integer Ans: E TEXT: presents examples using simple integers to show E is correct BUT I want to teach students an algebraic expression so they can deal with larger divisors than 10. Is this possible? I am an ESLteacher
