Definitions: A term in an algebraic expression can be a constant, a variable or a product of constants and variables separated by the signs of addition (+) or subtraction (-).
Examples: $27,\text{x},\text{xyz},\big(\frac{1}{2}\big)\text{x}^2\text{yz}$ etc.
The expression $3 x^2 y^2-5 x^2 y^2 z^2+z^2$ consists of three terms, i.e. $3 x^2 y^2-5 x^2 y^2 z^2$ and $z^2$. The coefficient of $3 x^2 y^2$ term is 3 .
