Compound interest happens when timelines are longer. Interest is applied at predetermined periods. Compound Interest is simply a bunch of Simple Interest formulae lined up together one after the other. What do I need to understand before reading this blog? Simple Interest Arithmetic: Adding and multiplying Pre-Algebra: Applying Exponents Algebra: Concept of "n" and "n-1" Algebra: Applying values to variables, Factoring, and the Distributive Property over Addition Click h

Simple interest happens when you borrow some money from someone for a short period of time, and they get paid back later with a little profit (or interest) for them.

Understanding financial calculations can be very intimidating. Rest assured that even the most complex financial equation is derived from very simple calculations at its core. To understand how mortgages work, how to make the best decision about trading in your car and starting a new car loan, or you simply want to build your skillset in financial math, you need to understand some basics. In this financial math series we will begin with the most basic calculations, Interes

By a psychologist working with moment.of.math Picture this. Your middle schooler sits down at the kitchen table, opens their laptop, and works through their algebra homework in about twenty-five minutes. No meltdown, no requests for help, no apparent struggle. You glance over and the screen shows a string of green checkmarks. Everything is done. You feel, briefly, like everything is fine. Then the unit test comes back. Or the PSAT. Or they hit the first week of eighth grade

Knowing how to solve an equation is only half the battle. Word problems test whether you can build the equation yourself, which is just as just as important as solving. Click here for some tips on linear equations Word problems in Algebra 1 fall into a few recognizable patterns: setting up a linear equation from a scenario, writing an inequality with a constraint, building a system of equations, and choosing between a linear and exponential model. The algebra is usually strai

Linear functions are the major component of Algebra 1. Master slope and the three equation forms and you'll recognize them everywhere, like in graphs, tables, word problems, and systems. Click here for some tips on linear equations Linear function questions come in a few forms: finding slope between two points, converting between equation forms, interpreting slope and y-intercept in context, graphing from an equation, and writing an equation from given information. Slope-inte

Polynomials are the foundation of quadratics and many other topics. Factoring is one of the key tools for solving them, so the more comfortable you become with factoring, the easier quadratics will feel. Click here for some tips on polynomials and factoring Polynomial questions in Algebra 1 cover adding, subtracting, and multiplying polynomials, and factoring in three main forms. Factoring also comes up inside quadratic solving, so these skills build. Here are some tips to ke

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
