4/7
But in the context of collecting like terms we have ALREADY DONE ALL MULTIPLIES AND DIVIDES, hence they're not mentioned in those chapters. Some people then incorrectly read between the lines here that Terms AREN'T separated by multiply and divide, but we have already seen a definition which doesn't even mention signs at all(!), as per several textbooks. Terms are separated by ANY operators. We can see then that 3(x-y) is a SINGLE TERM, as the only operator is INSIDE BRACKETS...

5/7 Lastly, Expressions. Expressions are made up of operators and operands (Terms/Products/Monomials). So, 1÷2 is an expression, 1 divided by 2, whereas ½ is a single term, grouped by a vinculum. In a single line we can represent the latter by putting it in brackets, (1÷2). It's important to understand that a Pronumeral CANNOT CONTAIN AN OPERATOR, UNLESS it's in Brackets, otherwise that would make it an Expression, NOT a Term. So 1÷2(b+c)=1÷(2b+2c), whereas (1÷2)(b+c)=(½b+½c)...
