Some maths:

$$\left( \begin {array}{cccc} {l_{11}} & {l_{12}} & {\cdots} & {l_{1 m}} \\ {l_{21}} & {l_{22}} & {\cdots} & {l_{2 m}} \\ {\vdots} & {\vdots} & { } & {\vdots} \\ {l_{m 1}} & {l_{m 2}} & {\cdots} &{l_{mm}}\end{array}\right) \left( \begin{array}{c}{\hat{b}_{1}} \\ {\hat{b}_{2}} \\ {\vdots} \\ {\hat{b}_{m}}\end{array}\right)=\left( \begin{array}{c}{l_{1 y}}\\ {l_{2 y}} \\ {\vdots} \\ {l_{m y}}\end{array}\right)$$

$$\mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ \frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \\ \frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0 \\ \end{vmatrix}$$

A real C++ Hello, world! program

#include <iostream>

int main(char argc, const char* argv[]) {
    std::cout << "Hello, world!" << std::endl;
    return 0;
}

That’s all. Thank you for your visiting!
