<p>I only <em>just</em> found out that calculators aren't allowed for the SAT Chemistry paper, and basically I'm freaking out because I can't do any questions without one.
Long division? I don't think so. And how on earth would I find ln2 and stuff like that?!</p>
<p>Help! I have about 7 weeks to get rid of my dependence on the calculator, any tips?</p>
<p>Isn’t the math purposely made ‘easier’ so you can do it without a calculator? If anything, just do easier chem practice problems and work your way up. If it’s MC questions, just get the right idea instead of fussing over sigfigs.</p>
<p>The test is written so that no problem requires more than basic math. Google up some elementary-school-level arithmetic and practice that. And if you need to use something like ln 2, they’ll give it to you.</p>
<p>ln2 = .693 (I think most people know that)</p>
<p>And the half life questions are really easy, like if the half life is 10 years how much of the sample will you have after 50 years.</p>
<p>0-1
10-1/2
20-1/4
30-1/8
40-1/16
50-1/32</p>
<p>1/32</p>
<p>i took it last year. the math in there is basic. </p>
<p>for example, a weak acid might want you to find the square root of 4.0<em>10^-2 (2.0</em>10^-1)</p>
<p>Thanks everyone! I’m really glad they simplify the math:)</p>
<p>you DEFINITELY won’t need to do ln…</p>
