Question:Does anybody know where I can find an online rational expressions calculator? Multiply, divide, addition, and subtraction.( Already tried mathway.com )
Answers:Try www.wolframalpha.com I entered (1/x + 1/y = ) and this online free program computed (x + y) / xy

Question:I have a lesson in Algebra II explaining how to multiply and divide rational expressions but it isn't as clear as I would like to be and I need help with some of my problems. Thank you, in advance!
4. (z^2z6)/(z6) * (z^26z)/(z^2+2z15)
5. (w^216)/(w) * (3)/(4w)
8. (4x^2y)/(z^3) * (2xyz)
9. (2p^3q^2)/(8p^4q) / (4pq^2)/(16p^4)
11. (y62 + 2y)/(y^2+y2) / (y+5)/(y^2+4y5)
**I need help on learning how to do these, not just answers. And, please don't waste your time telling me "to do my own homework".**

Question:I'm stuck with what to do here : (
(x+3(2x1) over x(x+4) *divided by* (x3)(2x+1) over x
does anyone know what to do, and also how to identify the restrictions? Any help would be appreciated. And I know you flip the second one, but i get confused there : ( Thanks!!
Answers:(x+3)(2x1)  ..x(x+4)  .(x3)(2x+1)  .....x ....(x+3)(2x1)............x = x  .......x(x+4)............(x+3)(2x+1) .........2x1 =  answer// .....(x+4)(2x+1)
Answers:(x+3)(2x1)  ..x(x+4)  .(x3)(2x+1)  .....x ....(x+3)(2x1)............x = x  .......x(x+4)............(x+3)(2x+1) .........2x1 =  answer// .....(x+4)(2x+1)
Question:i have these examples to study and im getting frustrated. have no clue how to do these! please help! i hve finals tomorrow!
MULTIPLICATION: (y^2)/(y1) * (y^2+y2)/(y^22y)
DIVISION: (x2)/(x+5) / (x+6)/(x^2+11x+30)
ADDITION: 7/(a+8) + 7/(a^264)
SUBTRACTION: (a^22a3)/(a^29a+18)  (a^25a6)/(a^2+9a+8)
Answers:1. y /(y1) * (y +y2)/(y 2y) = y(y)/(y1) * (y +y2)/y(y2) = y/(y1) * (y +y2)/(y2) = y(y +y2)/(y1)(y2) 2. (x2)/(x+5) * (x +11x+30)/(x+6) = (x2)/(x+5) * (x+6)(x+5)/(x+6) = (x2) * (x+6)/(x+6) = x2 * 1/1 = x2 3. 7/(a+8) + 7/(a 64) = 7/(a+8) + 7/(a+8)(a8) = 7(a8)/(a+8)(a8) + 7/(a+8)(a8) = (7a56+7)/(a+8)(a8) = (7a49)/(a+8)(a8) 4. (a 2a3)/(a 9a+18)  (a 5a6)/(a +9a+8) = (a3)(a+1)/(a6)(a3)  (a3)(a2)/(a+8)(a+1) = (a+8)(a3)(a+1) /(a6)(a3)(a+8)(a+1)  (a3)(a2)(a6)(a3 )/(a+8)(a+1)(a6)(a3) = [(a+8)(a3)(a+1) (a3)(a2)(a6)(a3)]/ (a+8)(a+1)(a6)(a3)
Answers:1. y /(y1) * (y +y2)/(y 2y) = y(y)/(y1) * (y +y2)/y(y2) = y/(y1) * (y +y2)/(y2) = y(y +y2)/(y1)(y2) 2. (x2)/(x+5) * (x +11x+30)/(x+6) = (x2)/(x+5) * (x+6)(x+5)/(x+6) = (x2) * (x+6)/(x+6) = x2 * 1/1 = x2 3. 7/(a+8) + 7/(a 64) = 7/(a+8) + 7/(a+8)(a8) = 7(a8)/(a+8)(a8) + 7/(a+8)(a8) = (7a56+7)/(a+8)(a8) = (7a49)/(a+8)(a8) 4. (a 2a3)/(a 9a+18)  (a 5a6)/(a +9a+8) = (a3)(a+1)/(a6)(a3)  (a3)(a2)/(a+8)(a+1) = (a+8)(a3)(a+1) /(a6)(a3)(a+8)(a+1)  (a3)(a2)(a6)(a3 )/(a+8)(a+1)(a6)(a3) = [(a+8)(a3)(a+1) (a3)(a2)(a6)(a3)]/ (a+8)(a+1)(a6)(a3)
