Question 861360
The remainder is <b>whatever the 68 doesn't cover</b>. Because 67 is less than 68, 2 67s is less than 2 68s. Therefore, only one 68 will fit into 67+67. In algebraic form:
{{{67+67=68+x}}}
Because 67 is only one less than 68, when you subtract 68 from both sides, it becomes 67-1, or 66. 

In non-algebraic form:
The answer is {{{67+67-68}}}
{{{67-1}}}
{{{66}}}
