x+27

difference is zero

"more than" means "added to" or "sum", so the two expressions mean the same thing

Now, if the two "a number" are not the same, then we have

x+27

y+27

difference is (x+27)-(y+27) = x-y, or the difference between the two numbers

**Quinton**, Monday, September 10, 2012 at 12:30pmwouldn't "the sum of twenty-seven and a number" be equivalent to 27 + y

**Steve**, Monday, September 10, 2012 at 2:16pmhmm. "sum" is addition, which is commutative.

That means that 27+y = y+27

Your suggestion is good, in that it follows the wording of the problem, but the value is the same as y+27.
