<p>I just wanted to ask whether CB gives problems with info unnecessary to solve the problem. It is usually the case that every word in a math problem sentence is very important but I do come into problems of whose some given conditions I don’t understand; or are they just unnecessary?</p>

<p>And I’d like to ask whether this problems here contains any unnecessary info.</p>

<p>If n>5, then in terms of n, how much less than 7n-4 is 5n+3?</p>

<p>How does the “n>5” part help in arriving at the solution?</p>

2

<p>the easiest way to solve this problem is to plug in. You want to plug in a number for n that is larger than 5, say 6. If you plug in 5 or lower, you might end up with a whacked out answer.</p>

3

<p>oh and the answser to ur other question is that all teh information almost always is needed. they don’t give out extraneous info. at all.</p>

4

<p>^ Not true. </p>

<p>Going back to your question, idk.</p>

5

<p>There are definitely some questions that have more info than you need. A lot of graphs and charts will have extraneous info.</p>
