Numbers are everywhere, from counting your steps to managing your allowance. The PSAT tests your ability to work with integers, fractions, decimals, and percentages.
Knowing how to add, subtract, multiply, and divide is the foundation of all mathematics. You'll also need to be comfortable with order of operations (PEMDAS), exponents, and roots.
We use these operations every day: splitting a bill, calculating discounts, or converting measurements. On the PSAT, you might need to compare values or find the result of a multi-step calculation.
Adding 3/4 and 1/2: Convert to common denominator, 3/4 + 2/4 = 5/4.
Calculating a 20% discount on a $50 shirt: \(50 \times 0.2 = 10\), so the sale price is $40.
Mastering numbers and how to use them forms the base of all PSAT Math.
