First of all, the correct grammar is to say "What areexamples of real numbers?" not "What is". Real numbers are any number from negative infinity to positive infinity. These include 1.555, 3, -6, -563.786, 10, etc. The only numbers that are no real numbers are imaginary numbers which involve the square root of negative numbers. It is immpossible to take the square root of a negative number so those numbers are not real.
