The sum of two even numbers is always what?
的意思是：
两个偶数的和一定是什么?
显然答案是：（it must be an even number.）一定是个偶数.
Name a prime number less than 13
的意思是：
举出一个小于13的质数.
回答可是：1,2,3,5,7,11中的任何一个.
solution通常是针对question 或 problem（即“问题”）而言的,可以是任何问题；而 sum of 只是用于求和、加总.
楼主要问“The sum of 与solution有什么区别”,这个问题从词义上就能区分——一个是求和,一个是泛指问题、难题的解决方法.
例如：
What is the sum of 1 and
What is the solution to 1 plus
两个句子的意思都是“1加2的和等于几?”
不同之处是,sum of 后面接两个需要相加的数字；而solution to 后面通常接具体的问题（在这里,问题就是“1 plus 2”）.
另外附送一个,solution与answer不一样的地方是：
answer一般只用于回答question,意为“问题的答案”；
而solution在部分情况下可以作为“问题的解决方法”来与question对应,但更多的时候是与problem对应,意为“解决麻烦、问题.”
一点个人心得,希望能帮上楼主的忙.
