Quick Answer. In mathematics the difference is the result of subtracting one number from another, and represents the operation of removing objects from a collection. Mathematicians use the term difference, because it shows by how much the two numbers in the subtraction problem differ. Continue Reading.
Finite Difference. In mathematics, finite differences deals with the changes that takes place in the value of the function, the dependent variable, due to change in the independent variable. Finite difference is a mathematical expression of the form $g(x + b)$ - $g(x + a)$. It is a technique to find the approximate value of the differential equations. The FD approximation for the derivatives is one of the old and easy way to solve differential equations.
