Question
Please help with the translation of this algebraic expression: Twenty-seven more than a number and the sum of twenty-seven and a number, what is the difference between the two? Thank you!

x+27
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

wouldn't "the sum of twenty-seven and a number" be equivalent to 27 + y
Steve
yes, if the number is "y"
Steve
hmm. "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.
