Free Math Homework Help

Help for homework problems can be found on many web sites. Some provide examples of homework problems along with answers and step-by-step solutions. Others explain math ideas and concepts. Many of these web sites are not free, however. When taking math courses at school, whether high school or college, many students have trouble doing the homework problems. They frequently get stuck doing a problem or don't know where to start. Even when looking for free math help online a few basic things have to be known.

Just as in any other subject, understanding math requires knowing some basic concepts. Before more advanced subjects in math can be taken, the rules and formulas in basic math must be understood. After whole numbers then come the negative whole numbers. The basic math operations such as addition, subtraction, multiplication and division are usually next. Learning multiplication usually involves learning the multiplication table, especially for the numbers that multiply to one hundred. Concepts such as factors and multiples are described that are used in higher math. Division is the inverse of multiplication. The process of division of sometimes leaves a result called a remainder.

It is very important to know fractions since they have wide application in the world and not just in learning math. The parts of the fraction are the numerator, denominator and a small line that separates them. The numerator goes on top of the line while the denominator goes below the line. This is because the fraction represents the division of two numbers.

Once fractions have been learned, the next topic in basic math is decimals. Fractions and decimals can represent the same number although the notation is different. The decimal point splits the number into two parts: a whole part and a remainder part to the right of the decimal point that is less than 1. In addition, it is important to convert between fractions and decimals in math.

When doing algebra, kids often have trouble with factoring and expanding polynomials. Even before this, however, the mathematical idea of variables has to be understood. Meanwhile, in trigonometry, they might have trouble with the trigonometry functions such as sine, cosine, tangent, secant, cosecant, and cotangent. The many formulas and terms used in algebra and trigonometry are important for taking higher math courses such as precalculus and calculus in addition to probability and statistics.

In precalculus, the concept of a function is used to describe a relationship between variables. Some of these mathematical rules and concepts are carried over from algebra. The most fundamental function that is learned is the linear equation. This is the function for a straight line. Other functions that are learned include rational functions, polynomial functions, exponential functions and logarithms.

In calculus I, concepts from precalculus such as a slope of a line is used to define the derivative. The derivative is used to find the rate of change that is taking place in a function. Along with the definition of a derivative, special rules have to be learned that rely on understanding rules from previous math.

The same can be said for calculus II. Calculus II deals with integrals. An integral is used to calculate the area under a function from the x-axis. Integrals are more complicated than derivatives because they sometimes require setting up a problem to fit a particular rule. Unlike derivatives, there might not be a solution unless numerical methods are used.

Calculus III deals with vectors and their functions. Special equations and formulas are used for vectors that are different for regular numbers which are called scalars. The dot product and cross product are two examples. All of the previous math that is learned in calculus II is applied in calculus III.

Probability introduces many new math formulas and definitions. Although there are many new concepts such as sample space, events, union and intersection, many of the old math concepts are applied as well. The binomial distribution is related to algebra through polynomials. The concept of probability distributions is carried over into statistics. The most important of these is the normal distribution. The parameters used are the mean and standard deviation. They are used in statistics to obtain confidence intervals and for hypothesis testing.

Unlike some other subjects, math requires learning previous math. By understanding and mastering current math courses, taking math in the future will be easier. If one is stuck, a review of prior math formulas, rules and equations can help break a difficult homework problem. There are many websites online that provide this free help for reviewing past math.
