**drwls**, Wednesday, September 8, 2010 at 5:55ama. Substitute 3 for a and 5 for s and compute.

27 + 30 = ___?

b. Does 9*(2a) + 6*(2s) = 2*(9a + 6s) ?

The order that three numbers are multiplied does not affect the result.

c. Does 9*(2a) + 6*(s/2) = (9a + 6s) ?

Put another way, does

18a + 3s = 9a + 6s

Not unless 3a = s
