Newton's law of Universal Gravitation?
Okay, so from my understanding, the equation is F=Gm1*m2/d^2. However, I see the equation written sometimes as F=G(m1*m2/d^2), which gives me a different answer. And sometimes, I see it written those ways but with an r instead of a d... So what's going on? Why are the equations different?

There are absolutely no difference between all of these formulas. r might be for radius when d is for distance. It doesn't matter. From mathematics, you should know that a*b is equal to a(b). Therefore, and again, there are no differences between the two formulas. You must be typing it wrong in your calculator.
