What terms are also expressions (none some ore all)?

Some

Step-by-step explanation:

Term and expression are two different concepts in mathematics. When numbers, symbols and operators are combined at one place to express or show some value, it is called expression. For example;

4y-3 or 3-1

It is an expression.

Where the term can be stated or defined as a single or smallest identity. Any number or variable or combination of them can be stated as term.

For example, if we take above expression 4y-3

4y-3, we can say that 4y is one term and 3 is second term.

Now the point to be noted here is, if you separately take 4y, it can be expressed as expression as well, because 4y is expressing value of something which is in accordance with the definition of expression.
