Misconception: When a variable is on both sides of an equal sign (i.e., x = x+1), students can get very confused.

    • This misunderstanding probably comes from learning about variables in math.
  • Students can find this concept counter-intuitive because they’re used to looking at the RIGHT side of the equation first!
