We're getting side tracked. Which of these do you agree with? We have to agree on all of them before we can do anything at all with math and units. Otherwise we can't communicate.


2x * 3x = 6x^2 ( that's 6*(x^2) )
2m * 3m = 6m^2 (like measuring the area of a room)

2x * 3 = 6x
2N * 3 = 6N

2x * 3y = 6xy
2N * 3s = 6Ns
2gallons * 3seconds = 6gallon-seconds

2m/s * 3s = 6m
2gallons/second * 3seconds = 6gallons
2kg.m/s/s * 3s = 6kg.m/s
