Scientific notation is a style of writing or representing numbers that pamper values that are too large or too small to be conveniently written in standard decimal notation. It has large number of useful properties and is mostly used in calculators and by mathematicians, doctors, engineers, and scientists.
Do you remember how we represent speed of light? Speed of light is given as 300,000,000 m/sec and we write it in scientific notation as 3 *108 m/sec. Scientific notation are developed by scientists to write the large values in small form. Scientific notation is based on powers of the base number 10.
The first number 3 is called as the coefficient and value of coefficient must be greater than or equal to 1 and less than 10. The second value is called as the base and it must be 10 when we deal with scientific notation. We always write the base number 10 in exponent form. In the case of speed of light, the number 3 * 108, the 8 is referred as the exponent or power of 10. When we use scientific nations then it makes complex calculation easy. Do you know that a Scientific Notation Calculator is developed to help students in solving the scientific problems. When you use this calculator you will easily convert the large number in smaller form. You will definitely enjoy solving scientific notation using this calculator.
After this let's study another math topic, statistics. It is the study of the collection, organization, analysis, and interpretation of data. It deals with all aspects of this, including the planning of data collection in terms of the design of surveys and experiments. In many articles I have explained you about online math help that you can use to solve math problems. Similarly, you can also solve your statistics problems with online statistics help.
To understand statistics in efficient way we need to understand few terms which we will use frequently in solving statistics problems. The very first term is "average". We all are intimated with this word from early age. In this, we add all the quantities and divide it by its number. Statistically average means Mean. Other term is Median; it is the "middle value" in given list. When the number of items present in the list is odd then median is the middle entry after sorting the list in increasing order. When the numbers are even then Median is equal to the sum of middle two entries divided by two. The last one is "Mode", it is defined as item or number that is occurring most frequently in the list. It is important to note that in a list there can be more then one mode, as more than one number can occur frequently. Sometimes we will ask to find the "range", it is simply the difference between the largest number and the smallest number of the list.
Linear inequalities is the inequality that contains linear function. We get an inequality equation when two numbers are connected by greater than or less than symbol. linear inequality is given as f(x) < b or f(x)
