Actually, students in Austrian
highschools are trained in doing such multiplications by hand ! |
No.2 | CAUTION with this example left for further testing. See smltest/IsacKnowledge/rational.sml 'SRM.test'. |

5*a * (a - b)^2 * (a + b)^3 / (7*b*(a - b)^3) * 7*b / (a + b)^3 = ... |
No.3 | x * y/(x*y - y^2) * (x^2 - x*y) = ... |
|
This term simplifies most. |
No.4 | (4*x^2 + 4*x + 1) * ((x^2 - 2*x^3) / (4*x^2 + 2*x)) = ... |
No.5 | (x^2 - 2*x) / (x^2 - 3*x) * (x - 3)^2/(x^2 - 4) = ... |
