<p>What do I do?</p>
<p>(4.5^2) + (3.33)^2 = ?</p>
<p>How do I round this? Should I round each term following the multiplication/division rules and then add them using the addition/subtraction rule?</p>
<p>Yes.</p>
<p>(Hey, baby, can I have your significant digits? :D)</p>
<p>dude ur sad if u cant do sig figs up to this time
unless u have a crappy teacher then nvm lol</p>
<p>Well, my physics teacher is inconsistent in her computations in class, so I am just making sure this is the right way.</p>
<ol>
<li>+ 11.1 = 31</li>
</ol>
<p>you actually dont need to know significant digits for the ap test at all. well mebe for frqs</p>
<p>You first work out the answer, without any previous roundings.</p>
<p>Then, with your final answer, cut it down to 2 sf. Because your smallest sf is 2 (from 4.5).</p>
