<p>While that’s true, any legit SAT example will never go as far as imaginary problems, which the problem the OP posted is testing.</p>
<p>I don’t think this problem was even going for imaginary problems. It was probably just the writer(s)’ mistake. Doesn’t it always say at the top of each math section that the problems only include real numbers?</p>
<p>That’s probably a more solid answer than mine is</p>
