According to AnthonyC, units, for some reason, behave like variables in algebra, e.g.
2x×4y simplifies to (2×4)xy, with arithmetic this computes to 8xy.
2x4y simplifies to 24xy, with arithmetic this computes to 0.5xy.
2x+4y or 2x−4y don’t simplify so that we could perform addition or subtraction.
So this algebraic behavior does indeed look like what we would expect from units.
