Term
A product of coefficients and any number of variables with exponents is called a term. Terms that have the same variables with identical exponents for each variables are called like terms.
Example:
3x,axy,4x2yz are terms. 3x+2 is not term: it is a sum of two terms.
3x2y and 7x2y are like terms since both have the same variables x and y with identical exponents: 2 for x and 1 for y.
Remember:
There cannot be any addition or subtraction in a single term.
Since multiplication is associative, rearrangements of variables does not change a term:3xy is same as 3yx.
3x2y and 7xyx are like terms.
