Comparing Real Numbers
Real numbers are numbers that include fractions, decimals, and whole numbers. When comparing real numbers, the larger number is called the 'greater' number and the smaller number is called the 'lesser' number. We can also compare real numbers by using symbols: <, >, or =.

compare real numbers
Real numbers are any number that can be found on the number line. This includes natural numbers, whole numbers, integers, fractions, and decimals.
Greater than and less than are comparison operations used to compare two real numbers. A > B means A is greater than B, while A < B means A is less than B.
Absolute value is the distance of a real number from 0 on the number line. The absolute value of a number is the same for both positive and negative numbers. For example, the absolute value of 4 and -4 is 4.

Real numbers are used to describe almost all physical quantities, such as the size of an object or the speed of a car. The set of real numbers is a superset of the set of rational numbers, which includes all fractions and integers. The real numbers are also used to represent irrational numbers, which are numbers that cannot be represented as fractions.
