<h1>order of operations</h1><br>
<div class = "lesson">
In the order of operations, you always multiply or divide numbers before
you add or subtract them, ignoring the order they are written. See if you
can solve these problems using that rule:
</div>
<form class="question">
<div>
<span class="q">
4 + 2 * 3
</span>
= <input type="text" class="answer">
</div>
<input type="submit">
</form>
<form class="question">
<div>
<span class="q">
(2 + 8) + 8 * 2
</span>
= <input type="text" class="answer">
</div>
<input type="submit">
</form>
<form class="question">
<div>
<span class="q">
(2 + 8) + 8 * 2
</span>
= <input type="text" class="answer">
</div>
<input type="submit">
