A rational number can be written as a ratio of two integers ie a simple fraction.
Sum of floor of irrational numbers.
The sum of two irrational numbers is not always an irrational number.
It depends on which irrational numbers we re talking about exactly.
Let s look at what makes a number rational or irrational.
Or will it be an irrational number.
Or could it be either.
In mathematics the irrational numbers are all the real numbers which are not rational numbers that is irrational numbers cannot be expressed as the ratio of two integers when the ratio of lengths of two line segments is an irrational number the line segments are also described as being incommensurable meaning that they share no measure in common that is there is no length the measure.
The sum of two irrational numbers can be rational and it can be irrational.
Well let s express that as the ratio of two other integers m and n.
So let s assume that this is going to give us a rational number.

So let s say that this first rational number we can represent as the ratio of two integers a and b.
And their sum gives us another rational number.
The product of two irrational numbers is not always an irrational number.
In division for all rationals of the form q 0 p q are integers two things can happen either the remainder becomes zero or never becomes zero.
This video covers this fact with various examples.
Yes yes the sum of two irrational numbers can be rational.
An irrational number is a real number that cannot be written as a simple fraction.
Will the sum of a rational and an irrational number be a rational number.
Let s call this irrational number let s just call this x.
