With arithmetic a little understanding can go a long way toward helping master math. Some math concepts may seem complicated at first, but after you work with them for a little bit, you may wonder what all the fuss is about. The English system of measurements is most commonly used in the United States. In contrast, the metric system is used throughout most of the rest of the world. Converting measurements between the English and metric systems is a common everyday reason to know math.

When you start with any value, then add a number to it and subtract the same number from the result, the value you started with remains unchanged.

When you start with any value, then multiply it by a number and divide the result by the same number except zero , the value you started with remains unchanged. The two Big Four that are commutative are addition and subtraction. The two Big Four operations that are associative are addition and multiplication.

The distributive property The distributive property connects the operations of multiplication and addition. A Guide to Working with Exponents, Radicals, and Absolute Value Exponents, radicals, and absolute value are mathematical operations that go beyond addition, subtraction, multiplication, and division. They are useful in more advanced math, such as algebra, but they also have real-world applications, especially in geometry and measurement.

Multiplication and division are inverse operations of each other. When you start with any value, then multiply it by a number and divide the result by the same number except zero , the value you started with remains unchanged.

An operation is commutative when you apply it to a pair of numbers either forwards or backwards and expect the same result. The two Big Four that are commutative are addition and subtraction. In other words. An operation is associative when you can apply it, using parentheses, in different groupings of numbers and still expect the same result.

The two Big Four operations that are associative are addition and multiplication. In other words,. Again, no matter which pair of numbers you multiply first, both problems yield the same answer: The distributive property connects the operations of multiplication and addition. Exponents, radicals, and absolute value are mathematical operations that go beyond addition, subtraction, multiplication, and division.

They are useful in more advanced math, such as algebra, but they also have real-world applications, especially in geometry and measurement.

Exponents powers are repeated multiplication: When you raise a number to the power of an exponent, you multiply that number by itself the number of times indicated by the exponent. Square roots radicals are the inverse of exponent 2 — that is, the number that, when multiplied by itself, gives you the indicated value.

Absolute value is the positive value of a number — that is, the value of a negative number when you drop the minus sign. Absolute value is used to describe numbers that are always positive, such as the distance between two points or the area inside a polygon. Clarity rating: 5 I was impressed with the clarity of the text. Easy-to-follow examples, lots of diagrams and clear instructions and descriptions.

Great book for the pre-algebra level student. Consistency rating: 5 The book is very consistent, the order is logical and very well thought through.

Each topic builds upon previously developed material. Modularity rating: 5 The modularity is based on the number systems: whole numbers, integers, fractions, etc. There are some algebra topics included.
