Misconception: When a variable is on both sides of an equal sign (i.e., x = x+1), students can get very confused.
- Students have difficulty when the same variable is on both sides of the equal sign
x = x + 1as opposed tox = y + 1. - 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!
