Our very own director was explaining this type of question from SAT and ACT exams for a student last week so we thought we might share it with you guys! Let’s break it down!

First, when you see a question on the math section that mentions a variable like ‘a number’ or ‘an integer’, you most likely need to plug in your own numbers. Here are the steps:

  1. Read through the question thoroughly and find LOGICAL numbers to insert. Easy numbers are usually better, so it might be best to go with a number like 2, 3, 4, 5, 10, or 100. Remember that the number 1 only works sometimes, so it is wise to avoid that pitfall.
  2. Solve the problem using your numbers.
  3. Check your answer with all of the answer choices to ensure accuracy.
  4. The number that fits is your correct answer choice!

 

Here is an example of this type of problem:

2122618027_e80db62572_o

 

First we chose 2 numbers for x and y, 3 and 6. These numbers add to 9 and make the first equation correct.

3 + 6 = 9.

Next we solved the second equation with the same variables.

9 – 6 = 3 and 3 / 3 = 1

The correct answer is (C).

So now you know! Don’t forget to PION when you are asked to come up with your own numbers to find the correct answer choice.
