I was doing a review question for "Scientific Notation Intuition" and it said to drag the decimal to match the top number (0.1558).
The movable answer started naturally at 0.1558 x 10^0, which is the answer, but it would let me choose it as the answer. I decided to just make it wrong and re-do a few more questions, and I changed the answer to 1.558 x 10^-1 and it said it was correct.
