<h1>1. About Discrete Mathematics</h1>
144+
145+
<h2>What is discrete mathematics?</h2>
146+
<p>Discrete mathematics is a branch of mathematics that can solve various problems. These include set problems, tree problems, and graph problems. While these problems may seem very difficult, using discrete mathematics makes solving them relatively easy. This effectiveness in addressing complex challenges is why discrete mathematics emerged as an important field.</p>
147+
148+
<h2>How do we use discrete mathematics?</h2>
149+
<p>First, you must know that should belong a branch of mathematics. Then you can use discrete mathematics.</p>
