"The force of gravity, F..."
So we start with just
F
"... is equal to..."
F=
"... the product of..." means we're going to multiply some things. What will we be multiplying together? Answer: "the gravitational constant (G), the mass of the first object (m1), and the mass of the second object (m2)..."
F = G × m1 × m2 ...
"... divided by..."
F = (G × m1 × m2) ÷ (...)
"... the square of..."
F=(G × m1 × m2) ÷ (...)^2
"...the distance between their centers (d)."
F=(G × m1 × m2) ÷ (d^2)
