### How to Perform Distribution in Algebra

Distributing items is an act of spreading them out equally. Algebraic distribution means to multiply each of the terms within the parentheses by another term that is outside the parentheses. To distribute [more…]

### How to Distribute Positive and Negative Numbers

When performing distribution, be aware of the sign being distributed and how that sign affects each term. Distributing a positive sign makes no difference in the signs of the terms — the signs stay the [more…]

### Combining Square Roots

Square roots, which use the radical symbol, are nonbinary operations — operations which involve just one number — that ask you, “What number times itself gives you this number under the radical?” Finding [more…]

### Formulas You Need to Know for Calculus

When 'studying calculus, you should have a good understanding of the following tables of formulas so you can efficiently and correctly solve calculus problems: [more…]

### Calculus For Dummies Cheat Sheet

Calculus requires knowledge of other math disciplines. To make studying and working out problems in calculus easier, make sure you know basic formulas for geometry, trigonometry, integral calculus, and [more…]

### Basics of Positive and Negative Numbers

Positive and negative numbers are all integers. Integers are whole numbers that are either greater than zero (positive) or less than zero (negative). For every positive integer, there's a negative integer [more…]

### How to Use Opposite Operations

When solving an equation in algebra, you will often use an opposite operation such as additive inverse or multiplicative inverse (reciprocal) to work your way toward the answer. You have to undo operations [more…]

### How to Subtract Fractions

You can subtract proper fractions that have different denominators — such as thirds and sixths — if you find the common denominator first. The biggest step in subtracting proper fractions is finding the [more…]

### How to Compare Numbers by Using Exponents

You can compare number values more easily when you use exponents, because numbers — especially large ones — can be deceiving. To discover the real value of a large number, write it as a number between [more…]

### How to Solve Problems Using Exponential Expressions

Using exponential expressions to solve problems that involve repeated actions is the best way to find the answer. Exponential expressions help you figure out problems that do the same thing over and over [more…]

### How to Raise Powers of Powers

When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. For example, in the following expression, x to the power of 3 is being raised [more…]

### Working with Negative Exponents

Negative exponents are a way of writing powers of fractions or decimals without using a fraction or decimal. You use negative exponents as a way to combine expressions with the same base, whether the different [more…]

### When to Distribute or Add First in Algebraic Distribution

When performing algebraic distribution, you get the same answer whether you distribute first or add what’s within the parentheses first. Deciding to distribute or add is a judgment call, based on the following [more…]

### How to Distribute Negative Signs with Variables

When you use negative signs and multiple variables in algebraic equations, the problems can look scary. Don’t worry, though. All you need to do is distribute the negative sign through, changing the signs [more…]

### How to Simplify Negative Exponents with Variables

Distributing with negative exponents means that you'll have fractional answers. A base that has a negative exponent can be changed to a fraction. The base and the exponent become the denominator, but the [more…]

### How to Distribute Trinomials

A trinomial, a polynomial with three terms, can be distributed over another expression. Each term in the first factor is distributed separately over the second factor, and then the entire expression is [more…]

### Understanding Basic Algebra Vocabulary

Knowing basic algebra vocabulary can help you translate key algebra words into algebra problems. By knowing the definitions of algebra vocabulary in this list, you will be able to construct and solve algebra [more…]

### How to Distribute a Polynomial

Distributing a polynomial isn't hard. When distributing a polynomial over any number of other terms, you distribute each term in the first factor over all of the terms in the second factor. When the distribution [more…]

### How to Distribute with Fractional Powers or Radicals

Distribution problems with fractional powers or radicals aren't as intimidating as they look. When distributing with fractional powers or radicals, remember that exponents that are fractions work the same [more…]

### How to Distribute Binomials

When you distribute in algebra, you multiply each of the terms within the parentheses by another term that is outside the parentheses. So, when you distribute a binomial over several terms, you just apply [more…]

### How to Recognize a Perfectly Squared Binomial

Recognizing a perfectly squared binomial can make life easier. When you recognize a perfectly squared binomial, you've identified a shortcut that saves time when distributing binomials over other terms [more…]

### Finding the Sum and Difference of the Same Two Terms

When distributing binomials over other terms, knowing how to find the sum and difference of the same two terms is a handy shortcut. The sum of any two terms multiplied by the difference of the same two [more…]

### How to Find the Sum of Two Cubes

Spotting a distribution that results in the sum of two cubes is a shortcut to solving distribution problems. To recognize what distribution results in the sum of two cubes, look to see if the distribution [more…]

### How to Find the Difference of Two Cubes

An expression that results in the difference between two cubes is usually pretty hard to spot. The difference of two cubes is equal to the difference of their cube roots times a trinomial, which contains [more…]

### How to Round Off Decimals and Fractions

You can simplify decimals and fractions by rounding off. To round off a decimal number, you limit the number of decimal places that the number holds. To round off a fraction, you first convert the fraction [more…]
