Yes, an expression can have many terms. e.g. 3x + 6y − 2ab + 4f − 2x2
3. Is a power the same as an exponent?
Yes, they can also be called "indices" as well!
4. What name is given to ordinary number terms in algebra?
Numbers on their own in algebra are called constants. e.g. In the expression 3x + 6, the 6 is a constant.
5. What does a dot mean in algebra?
