What&#x27;s interesting is the number of people posting here who found the questions ambiguous. One assumes that your average HN poster may be a little overly detail oriented (and privileged), but even so... what this seems to be testing as much as algebra skill is correctly parsing the question (assuming there is a single &#x27;correct&#x27; way to do that). Shouldn&#x27;t that skill be part of the reading comprehension testing? Ask any customer facing developer and they will tell you there is no single interpretation for most customer requirements.<p>My other concern was the answer to #1, namely, &quot;4m + 5b&quot; vs &quot;5m + 4b&quot;.  I feel like if you know it is in that form (sum rather than product) the two answer choices are just intended to trip people up who are moving through the test at speed.
