PERT Math Formulas You Need to Know
If you’re preparing for the PERT, knowing the key formulas cold can make the difference between placing into college-level math and landing in a developmental course. The Florida Postsecondary Education Readiness Test is heavily algebra-based, and a manageable set of PERT math formulas shows up again and again. This guide collects the formulas you most need to know, explains what each one does, and shows how to use them, so you can walk in with the essential math at your fingertips. Memorizing and, more importantly, understanding these formulas is one of the most efficient ways to prepare.
Because the PERT doesn’t provide a formula sheet, having these committed to memory is genuinely valuable. Below we’ll cover the formulas for equations, lines, quadratics, geometry, and more, paired with steady PERT math practice that turns memorized formulas into usable skills for a strong PERT math test result.
Why formulas matter on the PERT
The PERT math section centers on algebra and the foundational math college courses assume, and many of its questions hinge on applying a specific formula correctly. Unlike some tests, the PERT does not give you a formula sheet, so the formulas you know are the ones in your head. Being fluent with them saves time and prevents the errors that come from half-remembering a rule.
That said, memorizing formulas without understanding them is fragile. The goal is to know each formula and understand what it represents and when to use it, so you can apply it confidently even when a problem is phrased unusually. This guide pairs each formula with that understanding, which is what makes them stick and stay useful.
Linear equations and slope
Lines are everywhere on the PERT, so the slope-intercept form, y equals mx plus b, is essential. Here m is the slope and b is the y-intercept, the point where the line crosses the y-axis. This form lets you graph a line quickly and read its key features at a glance.
Equally important is the slope formula: the slope between two points equals the difference in their y-values divided by the difference in their x-values, often remembered as rise over run. Knowing both forms lets you find a line’s equation from points, identify slope and intercept, and answer the many PERT questions built around linear relationships.
Solving linear equations and inequalities
While not a single formula, the procedure for solving linear equations is a must-know: isolate the variable by performing the same operations on both sides. For inequalities, the same rules apply, with one crucial exception, when you multiply or divide both sides by a negative number, you flip the inequality sign.
That sign-flip rule is a classic PERT trap, so it’s worth committing to memory. Mastering the steps for solving equations and inequalities underlies a huge share of the test, because so many problems reduce to solving for an unknown. Practicing these procedures until they’re automatic is foundational PERT preparation.
The quadratic formula
For quadratic equations in the form ax squared plus bx plus c equals zero, the quadratic formula gives the solutions: x equals negative b, plus or minus the square root of b squared minus four a c, all divided by two a. This formula solves any quadratic, even those that don’t factor neatly, which is why it’s indispensable.
Knowing when to reach for it matters too: if a quadratic factors easily, factoring may be faster, but the quadratic formula always works. Memorizing it precisely, including the plus-or-minus and the order of operations under the square root, prevents the small errors that cost points. It’s one of the highest-value formulas to have ready.
Exponent rules
The PERT expects fluency with the rules of exponents. The key ones: when multiplying like bases, add the exponents; when dividing like bases, subtract them; when raising a power to a power, multiply the exponents; any nonzero base to the zero power equals one; and a negative exponent means the reciprocal.
These rules show up throughout the algebra questions, from simplifying expressions to working with polynomials. They’re compact and learnable, and knowing them cold lets you simplify quickly and accurately. Practicing exponent problems until these rules are second nature removes a common source of errors and slowdowns on the test.
Factoring and polynomials
Factoring is central to PERT algebra, so know the common patterns: factoring out a greatest common factor, factoring trinomials into two binomials, and the difference of squares, where a squared minus b squared factors into a plus b times a minus b. Recognizing these patterns quickly speeds up many problems.
The difference-of-squares pattern in particular is worth memorizing as a formula, since it appears often and is easy to miss. Combined with the FOIL method for multiplying binomials, first, outer, inner, last, these factoring skills let you handle the polynomial questions the PERT includes. Practice spotting and applying these patterns until they’re automatic.
Geometry formulas: area and perimeter
The PERT includes some geometry, so know the basic area and perimeter formulas. The area of a rectangle is length times width, and its perimeter is twice the sum of length and width. The area of a triangle is one-half base times height. The area of a circle is pi times the radius squared, and its circumference is two pi times the radius.
These formulas come up in both pure geometry questions and applied word problems, so having them ready saves time. They’re a small, finite set, easy to memorize with a little practice. Knowing them confidently means you can focus on setting up the problem rather than scrambling to recall the right formula.
Volume and the Pythagorean theorem
For three-dimensional figures, know that the volume of a rectangular prism is length times width times height, and the volume of a cylinder is pi times the radius squared times the height. These appear in applied problems about capacity and space.
Also essential is the Pythagorean theorem: in a right triangle, a squared plus b squared equals c squared, where c is the hypotenuse. This lets you find a missing side of a right triangle and underlies many geometry and coordinate-plane problems. It’s one of the most useful formulas in all of math, and the PERT expects you to know it.
Percentages, ratios, and proportions
Many PERT word problems involve percentages and proportions. Remember that a percentage is a part over a whole times one hundred, and that to find a percent of a number you multiply by the decimal form of the percent. For proportions, set two ratios equal and cross-multiply to solve for the unknown.
These relationships drive a large share of the applied problems, from discounts to rates to scaling. Being fluent with converting between fractions, decimals, and percentages, and with setting up proportions, lets you handle these efficiently. They’re not flashy formulas, but they’re among the most frequently used skills on the test.

How to memorize formulas effectively
The best way to memorize PERT formulas is through use, not flashcards alone. As you practice problems, you’ll naturally reinforce the formulas you need most. Writing each formula out as you use it, and explaining what each part means, helps cement both the formula and its purpose in your memory.
Focus your memorization on understanding, not rote repetition. When you know why the slope formula is rise over run, or what each term in the quadratic formula does, the formula becomes far easier to recall and apply correctly. Pair this understanding with regular practice, and the formulas will be there when you need them on test day.
