Here is the solution to yesterday’s Mathematics Knowledge example.  In my ASVAB prep course, I make sure to focus on the 2 math sections of the ASVAB: Arithmetic Reasoning and Mathematics Knowledge.  Knowing algebra and geometry with help to improve your math score in the section of Mathematics Knowledge.  I tell my students it is the easiest section to improve upon.  As someone who tutors for this exam, I want to remind you to focus on knowing the formulas for Mathematics Knowledge.  The exam will not provide the formulas.  You need to know them on your own.  This example is a  case of factoring in algebra. Factoring in algebra is a  very common topic and is a must know for this section of the ASVAB.
