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
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

When presented with problems of this type, you just have to examine the cases to see which one does not fit. There are no algebraic methods as far as I can see.
