(by Matthew M. with help from Sage the intrepid student dog) "Integer operations" just means working with positive and negative whole numbers. The key question here is: Should the answer get bigger or smaller? Asking yourself this question will make it easy to tell when an answer isn't right. Don't worry if you find this confusing: Our intrepid canine student, Sage, is not sure about this yet. Read and work along as our intrepid canine student Sage reviews how to work with I

Are you taking algebra in the fall? The good news is, you have probably already used it before: If one game item does more damage but another takes less time to reload, which one is actually better? If a hoodie is “30% off” but shipping gets added at the end, is it still a good deal? If someone says one player is better because they scored more points, what happens when you compare minutes played, games missed, or shots taken? That’s what algebra can be used for: finding miss

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

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
