Key Takeaways
- When we have variables in our answer choices or we see the phrase ‘in terms of’ we can select numbers for those variables to get our answer
- We must avoid picking unhelpful numbers like 0, 1, fractions, and negatives in order to make things as clean as possible
- Once we have selected our numbers, we get a numerical answer, and then plug the numbers into the answer choices to find a match
- We must test all the answer choices, because depending on our numbers more than one may work
