Different types of real numbers

Of course, mathematics is most clearly applicable to philosophy where it intersects with the mathematically hard sciences, like physics However, philosophy in general, and metaphysics in particular, isn’t as neat as mathematics because it must engage with the messiness of the world to help us ascertain its truths

Without zero there would be: No algebra, no arithmetic, no decimal, no accounts, no physical quantity to measure, no boundary between negative and positive numbers and most importantly- no computers!

• Natural numbers: These are real numbers that have no decimal and are bigger than zero
• Whole numbers: These are positive real numbers that have no decimals, and also zero
• Integers: These are real numbers that have no decimals

Imaginary numbers are numbers that cannot be quantified, like the square root of -1 The number, denoted as i, can be used for equations and formulas, but is not a real number that can be used in basic arithmetic You cannot add or subject imaginary numbers Another example of an imaginary number is infinity

Below is a diagram of the real number system Real numbers are mainly classified into rational and irrational numbers Rational numbers include all integers and fractions All negative integers and whole numbers make up the set of integers Whole numbers comprise of all natural numbers and zero

A googol equals 1 followed by 100 zeros Googol is a mathematical term to describe a huge quantity Googol, a quantity that surpasses even the number of hydrogen atoms in the observable universe, is a number dating back to the mid-1900s and is still used by mathematicians today
