Rational Numbers are a subset of the Real NumbersĬombinations of Real and Imaginary numbers make up the Complex Numbers. Integers are a subset of Rational Numbers The values a and b can be zero, so the set of real numbers and the set of imaginary numbers are subsets of the set of complex numbers. Statement 3 - No real numbers are irrational numbers. All natural number are rational numbers, but not all rational numbers are natural numbers. Statement 2 - Some rational numbers are natural numbers. The real numbers are made up of rational numbers and irrational numbers. The "unit" imaginary numbers is √(-1) (the square root of minus one), and its symbol is i, or sometimes j.Ī combination of a real and an imaginary number in the form a + bi, where a and b are real, and i is imaginary. All real numbers are NOT rational numbers. For example 2×2=4, and (-2)×(-2)=4 also, so "imaginary" numbers can seem impossible, but they are still useful! Some rational numbers are natural numbers All whole numbers are integers Some integers are natural numbers. If you square a real number you always get a positive, or zero, result.

It comes from the Italian "Quoziente".Īny real number that is not a Rational Number. Identify real numbers from the list of numbers-18, 11, frac. we can estimate between which two rational numbers is a real number and place it on the number line. If we can order real numbers, then we can add, subtract, multiply and divide real numbers.

Q is for "quotient" (because R is used for the set of real numbers): the result of dividing one number by another. All real numbers lie on the number line, so, they can be compared and ordered. The numbers you can make by dividing one integer by another (but not dividing by zero).

( Z is from the German "Zahlen" meaning numbers, because I is used for the set of imaginary numbers). (Or from 0 upwards in some fields of mathematics).
