the expected value and the observed value difference of a function is called mean of deviation. The mean deviations absolute deviations mean of a set of data about the data's mean. It is an important expressive statistic that is not frequently used in mathematical statistics. This is basically mean deviation as the "mean deviation from the mean," the introduction of the complete value makes logical calculations using this statistic much more difficult.
A part from the algebra is defined as the pre algebra which uses the numbers and letters in problems with simplicity in solving the problems and it is also used in calculating distances. The pre algebra that is used here is contains dissimilar topics. Exponents, linear equations, integers, square roots, and fractions are included in pre algebra. Pre algebra also includes factors which is prime and also the numbers which is prime.
An unknown quantity is called a variable.
A statement or equality of two algebriac expressions involving a variable is called an equation.
An equation which contains only one varaible of degree 1 , is called a simple linear equations.
A word problem is a mathematical problem stated in words.
