Forgetful distribution

Algebra Level 4

When first introduced to multiplication in algebra, a common mistake made by students is to claim that a×(b+c)=a×b+c, a \times ( b + c) = a\times b + c, because they forget to distribute aa properly. For how many ordered triples of integers (a,b,c) (a, b, c) , each of which are between 0 and 10 inclusive, do we actually have a×(b+c)=a×b+c? a \times ( b + c) = a\times b + c?
