True or false
The polynomial 79xy is called a binomial. 

False.  That's a monomial because there is only
one term.  There are no additions or subtractions.

MONOmials have ONE term -- no additions or 
subtractions.
Examples:  79xy is a monomial, 5z is a
monomial, -6x%5E4y%5E2z%5E8 is a monomial,
x is a monomial, 3 is a monomial.

BInomials have TWO terms -- one addition or subtraction.
Examples: 2x%2B3y is a binomial, -6x%5E4y%5E3-7y%5E2z is
a binomial, x-1 is a binomial.

TRInomials have THREE terms -- two additions or subtractions.
Examples: 7x%5E2%2B3x-5 is a trinomial, -3x%5E2y%5E6-27y%5E4z%5E3%2B3xyz is
a trinomial, -x-5-z is a trinomial.

If a polynomial has four or more terms, we just call it
a "polynomial".
