<p>are you allowed to have 2 on the table at once? im used to my old ti 83 but the ti 89 i just got can do some stuff more quickly than the old.</p>
<p>please answer - i'm taking this test tomorrow morning.</p>
<p>I don't think it should be a problem... but who knows, it might depend on the instructor</p>
<p>No, it is not allowed.</p>
<p>why isnt it allowed? what if i just had 1 on the table at a time, and switched during the test?</p>
<p>You should ask your proctor before you start the tests tomorrow. Since it doesn't seemed to be defined in the rules, the multiple calc things will probably based on their discretion.</p>
<p>thanks, i'll be sure to ask</p>
