<ul>
<li><span style="color:#e74c3c;">Property 1</span>: Adding number $a$ to number $b$ is the same thing as adding number $b$ to number $a$.</li>
</ul>
<p>$$a+b=b+a$$</p>
<ul>
<li><span style="color:#e74c3c;">Property 2</span>: Brackets have no impact when we are just multiplying or adding: $$3 + (4 + 5) = (3 + 4) + 5 = 3 + 4 + 5$$ $$3 \times (4 \times 5) = (3 \times 4) \times 5 = 3 \times 4 \times 5$$</li>
<li><span style="color:#e74c3c;">Property 3</span>: The distributive law: $$a (b + c) = a \times b + a \times c$$</li>
<li><span style="color:#e74c3c;">Property 4</span>: $0$ added to a number returns the number itself, and $0$ multiplied by a number returns $0$.</li>
</ul>
