Critically, the result is not simplified. You need n*(n+3)/4, a
result that I suspect you will find harder to obtain since it requires
a gcd calculation. Can you do that?

Thanks for your response.

It doesn't do gcds but it does do prime factoring.
- 1 click to factor the 16
- 1 click to factor the 12
- Click the plus to collect the 3s <- This step to be improved when I
implement common factoring with drags
- Click the divide bar to cancel common factors (first the 3's must
both be dragged to the left of numerator and denominator)
