I have included a video on PEMDAS, which is also known as order of operations. This is an important topics in Mathematics Knowledge on the ASVAB. This video includes a type of question that I cover in my ASVAB prep course. Without studying PEMDAS, ASVAB math help is incomplete. Anyone who tutors for the ASVAB will be able to tell you the value of knowing how to correctly perform problems which involve the order of operations. PEMDAS refers to the steps Parentheses, Exponents, Multiplication or Division whichever comes first, and finally Addition or Subtraction whichever comes first. Enjoy the video!
