If the symbols $$\triangle,\Box, \odot, \diamondsuit$$ stand for the arithmetical operations of addition, subtraction, multiplication and division respectively, then $$\frac{1\triangle (402)}{(5\odot2)\Box (6\triangle 3)}$$ =
If + represents division, - represents addition, $$\times$$ represents subtraction and $$\div$$ represents multiplication, then
$$7 \div 3 - 5 \times 8 + 2 $$=
If a stands for +, $$\beta$$ stands for =, $$\gamma$$ stands for < and $$\delta$$ stands for > , then a $$\alpha$$ b $$\beta$$(2c) and b $$\gamma$$ c implies
If $$\frac{(12)^{4}.(20)^{3}.(45)^{3}}{(6)^{3}(15)^{4}(10)^{2}} = 2^{\alpha}.3^{\beta}.5^{\gamma}$$, then $$2\alpha + 3\beta + 5\gamma$$ =
