Use our guide to get instant feedback on every step so you see your mistakes and fix them before the exam. You're probably doing algebra the hard way You solve a problem, check the answer key, and realize you got it wrong. But you don't know why, and you wasted 10 mins without learning anything. This page is different. As you solve, our AI tells you if each line is correct or not. So you catch mistakes while you're practicing, not after. Watch: type a step and moment.of.math

No algebra required. These are some of the most approachable questions on the exam — just division and careful reading. Two-way table questions give you a grid of data and ask for a percentage. The only trick is finding the right denominator. The question tells you which group to look at — that group's total goes on the bottom of your fraction. Click here for some tips on statistics Three steps — every time 1. Re-read the question and find the group being asked about. Underli

Once you know a handful of rules, exponent questions become fast, reliable points. Compound interest is on almost every exam. The Regents tests exponent rules — multiplying powers, raising a power to a power — and exponential growth, which is what happens when something multiplies by a constant rate each period. Compound interest is the classic example. Click here for some tips on exponents and compound interest Rules worth knowing xᵃ × xᵇ = x^(a+b) (multiply → add exponents

Quadratics show up in both Part I and the longer constructed-response questions. Worth knowing cold. Click here for some tips about quadratics Quadratic questions come in a few forms: factoring a polynomial, solving by factoring or the quadratic formula, interpreting a parabola from a graph, and working with real-world height problems. The golf ball problem is practically a Regents staple at this point. Your toolkit Standard form: ax² + bx + c = 0 Axis of symmetry (x-coordina

Function problems on the Regents are mostly about reading carefully and applying slope-intercept form correctly. The Regents tests functions a few consistent ways: identifying whether a relation is a function, interpreting the parts of a linear equation in context, and reading transformations of parabolas. Once you know what to look for, these are reliable points. Click here for tips on reading and interpreting functions The essentials A relation is not a function if any x-va

Learn to spot the two equations hiding inside any real-world setup. Every system gives you two facts about two unknowns. Write those facts as equations, then solve. The Regents loves coin problems, pricing problems, and age problems — they look different but use the exact same method. The trick is about setting each unknown as one half of an equation, then using one of the two methods below to find the answer of one equation by using the other! Click here for some tips on sys

The most tested topic on the Regents. Get this right and you've already well on your way in points. Click here for some tips on linear equations Linear equations show up everywhere — solving for a variable, rearranging formulas, writing inequalities from word problems. The reliable process: isolate the variable by undoing operations in reverse order. Undo addition and subtraction first, then multiplication and division. What to Know Cold: Slope-intercept form: y = mx + b (m
