Just multiply the coefficients, leave the variable the same, and add the exponents.
No.
It depends on whether you are working with variables. You cannot add terms with variables that have unlike exponents.
If you have like terms then to multiply you add the exponents and to divide you subtract.So, x2 * x3 = x5 and y7 / y5 = y2Also, for example, 2x2 * x3 = 2x5 (we can do this as the terms are like; x's only)But if you do not have like terms then this does not apply.For example, x2 * y3 does not equal xy5.

You can't. You can only subtract like terms. Like terms must have exactly the same variables and exponents on the variables.

are known as like terms.
If you are multiplying powers of the same base (like 24 times 211), yes, you add the exponents.
you do not do anything when you add numbers with exponents. you just figure out the answer. it is only if you multiply numbers with exponents, where you add the exponents..
To add polynomials with dissimilar terms, you simply combine like terms by collecting the terms with the same variables and exponents. If a variable or exponent is not present in one polynomial, you leave it as it is. Then, you can add or subtract the coefficients of the like terms to arrive at your final answer.
