He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. 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.
