\section{Introduction}

\begin{frame}
    \frametitle{Latex and Beamer}
    
    LaTeX is a high-quality typesetting system; 
    it includes features designed for the production of 
    technical and scientific documentation.

    Beamer is a LaTeX class to create powerful, 
    flexible and nice-looking presentations and slides. 
    
    The beamer class is focussed on producing (on-screen) presentations, 
    along with support material such as handouts and speaker notes.

\section{Beamer Basic}
\subsection{Hightlight}

\begin{frame}
    \frametitle{Block and Alert}

    \begin{block}{Pythagorean theorem}
        \vspace*{-\baselineskip}\setlength\belowdisplayshortskip{0.6pt}
        $$a^2 + b^2 = c^2$$
        % \vspace*{-\baselineskip}\setlength\belowdisplayshortskip{0.1pt}
        where c represents the length of the hypotenuse and 
        a and b the lengths of the triangle's other two sides.
    \end{block}
    
    \begin{alertblock}{Remark}
        \begin{itemize}
            \item the environment above is \alert{block}
            \item the environment here is \alert{alertblock}
        \end{itemize}
    \end{alertblock}

\end{frame}

\begin{frame}
    \frametitle{Proof}

    \begin{block}{Pythagorean theorem}
        \vspace*{-\baselineskip}\setlength\belowdisplayshortskip{0.1pt}
        $$a^2 + b^2 = c^2$$
        % \vspace*{-\baselineskip}\setlength\belowdisplayshortskip{0.2pt}
    \end{block}
    
    \vspace{0.4cm}

    \begin{proof}
        \vspace*{-\baselineskip}\setlength\belowdisplayshortskip{0pt}
        \begin{align*}
            &3^2 + 4^2 = 5^2\\
            &5^2 + 12^2 = 13^2
        \end{align*}
        % \vspace*{-\baselineskip}\setlength\belowdisplayshortskip{0pt}
    \end{proof}

\begin{frame}{Columns}
    \begin{columns}
        \column{0.5\textwidth}
        This is a text in first column.

\subsection{Math}

\begin{frame}{Equation1}
    A matrix in text must be set  smaller:
    $\bigl(\begin{smallmatrix}
    a&b \\ c&d
    \end{smallmatrix} \bigr)$
    to not increase leading in a portion of text.

    \[ f(n) =
    \begin{cases}
        n/2       & \quad \text{if } n \text{ is even}\\
        -(n+1)/2  & \quad \text{if } n \text{ is odd}
    \end{cases}
    \]

    $$50 apples \times 100 apples = lots of apples^2$$

    $$\sum_{\substack{0<i<m \\ 0<j<n }} 
      P(i,j)=\int\limits_a^b\prod P(i,j)$$

    $$P\left(A=2\middle|\frac{A^2}{B}>4\right)$$

    $$( a ), [ b ], \{ c \}, | d |, \| e \|,
    \langle f \rangle, \lfloor g \rfloor,

\end{frame}

\begin{frame}{Equation3}
    $$Q(\alpha)=\alpha_i\alpha_jy_iy_j(x_i\cdot x_j)$$

    $$Q(\alpha)=\alpha^i\alpha^jy^{(i)}y^{(j)}(x^i\cdot x^j)$$
