Distance is the complete length of its path between any two points. Denoted by d. Displacement is the shortest path between any two points when measured along the minimum path between them. Denoted by s. The displacement can be positive, negative or zero. Distance is always positive. Distance depends upon the path travelled by the body. Displacement depends upon the initial and final positions ...

Linear Equation is an Equation in which the highest power of the variable is always 1. It is also know as one degree equation. Linear Equation is in form of Y=mx b.

Prime Number is a positive number which has exactly two factors that is it can be divided by only 1 and itself. Composite numbers is a positive number which has more than two factors.

Natural Numbers are positive numbers which originate from 1 to infinity. Denoted by N symbol. Natural Numbers does not include fraction and irrational numbers. Whole Numbers are same as natural numbers but starts with zero. Whole Numbers also does not include fractions and irrational numbers. Whole Numbers are denoted by W.
