For positive integers m, n define in $$m\oplus n = 2m - n$$ and $$m * n = m + 3n$$ then $$(2 \oplus 3) * (4 \oplus 5)$$ =
If $$x* y = x + y + xy$$ and $$p \phi q= \frac{p+q}{p-q}$$, then $$(5\phi3 )(14\phi12)$$
If a $$\otimes b = (a + b - 1)^{2} - 1$$, then $$( 1 \otimes 2) \otimes ( 3 \otimes 3)$$ =
If $$p = \frac{a-b}{a+b}, q = \frac{b-c}{b+c}, r = \frac{c-a}{c+a}$$, then $$\frac{1+p}{1-p}, \frac{1+q}{1-q}, \frac{1+r}{1-r}$$ =
