I am from Hong Kong.

Divide by zero is not defined.

Thanks Melody. I have had a wonderful holiday :D

9152 x 1027 + 10000000 - 4452523 = 14946581

The numbers are soooo random LOL.

Less random pattern.

(10 + 3) x (2000000 - 850263)

$\sqrt{\dfrac{75}{2}}-\sqrt{\dfrac{3}{2}}\\=\dfrac{\sqrt{75}}{\sqrt{2}}-\dfrac{\sqrt{3}}{\sqrt{2}}\\ =\dfrac{5\sqrt3}{\sqrt2}-\dfrac{\sqrt3}{\sqrt2}\\=\dfrac{4\sqrt3}{\sqrt2}\\=\dfrac{2\cdot\sqrt2\cdot\sqrt2\cdot\sqrt3}{\sqrt2}\\ =2\sqrt2\cdot\sqrt3\\ =2\sqrt6$

$\text{Questions:}\\ \text{1. Why is sqrt 75 = 5 sqrt 3?}\\ \text{sqrt 75 = sqrt 25 x sqrt 3 = 5 sqrt 3}\\ $

sinh(2ln x)

= $\dfrac{1}{2}(e^{2\ln x}-e^{-2\ln x})$$\text{<----By definition}$

=$\dfrac{(e^{\ln x})^{2}}{2}-\dfrac{1}{2(e^{\ln x})^{2}}$

=$\dfrac{x^2}{2}-\dfrac{1}{2x^2}$

85/5 is a whole number which is 17.

I don't know, but you can just type abs().
