Meet Prepster, your personal AI tutor

Sample session

Prove that the sum of two even integers is even.

  1. Student: Even numbers end in 0, 2, 4, 6 or 8, so the sum does too?

  2. Good instinct to look for a pattern! How could you write any even number with a variable, so your argument works for every case?

  3. Student: Maybe as 2k2k?

  4. Exactly. Now write the second even number the same way and add them. What do you notice?
