<p>Are they? They're not in any of my practice books but someone told me they were. What do you think? ...thanks</p>
<p>Since everyone just 'jumped' to answer my question, I did a little research and found out that no, matrices are not on the test, FYI.</p>
<p>thats good. i don't remember how to do them.</p>
<p>just enter them into your calculator and play around with them and you should find the answer</p>
<p>I think determinants are, though.</p>
<p>yea you're right, i remember seeing that on a practice test like a week ago</p>
<p>Same here. And I had to skip it... I couldn't remember how you use them to solve systems of equations :(</p>
<p>it wasn't on my test lols</p>
<p>Reality:
You must know how to find a determinant of a 2x2 or 3x3.
You must know what the term "coefficient matrix" refers to in systems of equations.
You need to know that you can only multiply an m x p by a p x n matrix, and that you'll get a m x n matrix.
You need to know basic matrix multiplication.
Only determinants and multiplication can be handled by the calculator.
The rest are concepts.
All of the above have appeared on actual Math 2 exams.</p>
<p>I saw a matrix problem on the 11PR SATI book. That was really weird.</p>
<p>Last year when I took it, no matrices</p>
<p>They won't ahve more than 1, so skip it? If not, learn a little of the basics or how to do it on your calculator!! :)</p>
<p>There was a matrix question on June 2004 SAT II math IIC.</p>
