Basics of Mathematics

Basic math is nothing but the simple or basic concept related with mathematics. Generally, counting, addition, subtraction, multiplication and division are called the basic math operation. The other mathematical concept are built on top of the above 4 operations. These conepts along with different type of numbers, factors, lcm and gcf makes students ready for learning fraction.

Along with the concept of these operation, we need to understand the different properties of these operation as well as relation among these operations.

At iPracticeMath, we believe that to enhance and embibe these concept, it is good to practice math-problem using step-by-step math practice test and worksheets.

The speed and accuracy acquired by practicing makes you ready for next set of concepts - factors, number theory, multiples, least common multiples and greatest common factors .

Numbers

NATURAL NUMBERS {1, 2, 3, 4, 5, …}

WHOLE NUMBERS {0, 1, 2, 3, 4, …}

INTEGERS {…, 3, 2, 1, 0, 1, 2, …}

RATIONAL NUMBERS All numbers that can be written in the form , where a and b are integers and . IRRATIONAL NUMBERS Real numbers that cannot be written as the quotient of two integers but can be represented on the number line. REAL NUMBERS Include all numbers that can be represented on the number line, that is, all rational and irrational numbers. PRIME NUMBERS A prime number is a number greater than 1 that has only itself and 1 as factors. Some examples: 2, 3, and 7 are prime numbers. COMPOSITE NUMBERS A composite number is a number that is not prime. For example, 8 is a composite number since 8 = 2 *2 * 2 = 2 to the power 3.
