exponents, all done, don't know what x^2 is
multiplication or division
addition or subtraction
(x^2)+(7x)+(6/x)+1
to simplify, make them all fractions with the deonmenator (bottom number) x
x^2 times x/x=(x^3)/x
7x times x/x=(7x^2)/x
6/x=6/x
1 times x/x=x/x
so
((x^3)/x)+((7x^2)/x)+(6/x)+(x/x)=(x^3+7x^2+6+x)/x
