add comment about convention in rings with mixed addition and multiplication #123

Closed dcernst closed 2 years ago

dcernst commented 5 years ago

When we have a mixture of multiplication and addition, the standard conventions (i.e., PEMDAS) hold. For example, when we write ab+c, this is short for (ab)+c and NOT a(b+c).

Done.
