In this episode you will learn:
- To master PEMDAS, you must apply the left-to-right rule for multiplication/division and addition/subtraction pairs.
- When adding or subtracting fractions, always find the least common denominator first; for division, remember to invert and multiply the second fraction.
- A double negative becomes a positive, such as in the expression -7 - (-10), which simplifies to -7 + 10.
- Use estimation as a mental check to quickly eliminate incorrect answer choices, especially with fraction and decimal problems.
- Since the OAR Math Skills Test is adaptive and calculator-prohibited, accuracy on fundamental arithmetic is crucial for achieving a competitive score.
