Explanation:
trick question alert !
because a term is every part of an expression. and they are storage by + or - signs.
and sometimes also by division !!!
so, what did your teacher tell you ?
and then every grouping of these single parts in the expression is a term too.
therefore the whole expression is a term too.
so, the expression itself is a term.
then 3 is a term.
then 1/2×b is a term.
that is in total 3.
but it could be that 1×b (or simply b) and 2 of the fraction or division are considered terms too.
that would bring us to 5.
but normally the answer should be 3.
