Does anyone else have a problem with translating what you learn in the math guide into useful information on the Practice problems.
For example, I have covered Integers, Primes, Factors, and Multiples.
However, for example:
if n = 20! + 17 than n is divisible by which of the following? 15, 17, or 19? I have no idea how learning about the above topics prepares me to answer this question at all. I had no idea how to even start solving the problem until Greg explained at which point I was like “ok that’s super easy, but how was I supposed to know to do that based on what I have learned thus far”
another example is the following:
if n is a positive integer and the product of all integers from 1 to n, inclusive, is a multiple of 999 what is the least possible value of n…
once Greg explains it in the video it makes sense, but I have no idea how I am supposed to arrive at that with just the basics of the above-mentioned topics.
Am I just too early in the process and missing certain topics or what?
