The answer depends on the context. Some examples:
In Algebra, a like term is a term where it shares either a common variable or common constant.
Alg.
secret
They are called "like terms".
Unlike terms.
Yes, 6 and 9y are unlike terms. The 6 is a constant and 9y is constant attached to a variable.
No. You can't subtract unlike terms
Unlike terms are terms in an equation that are different. These terms cannot be combined. Like terms, however, can be combined.
Unlike terms.

They are called "like terms".
A term is a constant number, a variable, or a variable with a coefficient. Terms are separated from each other by addition or subtraction signs. For example, -7x is a term. 3xy is a term. 4b+m is two terms.
Unlike terms.
No, they do not. Although it is using letters to represent numbers, Roman numbers are fixed symbols, unlike letters in algebra which represent variables.
What does 3n mean in algebric terms
Yes, 6 and 9y are unlike terms. The 6 is a constant and 9y is constant attached to a variable.
