Integers are only the positive and negative whole numbers, and zero. Like ... -3, -2, -1, 0, 1, 2, 3 ... Where real numbers are all those, but plus all the fractions and decimals in between. In fact, it contains the integers, and the rational numbers and the irrational numbers. Real numbers is the largest group there is of types of numbers.

An integer is a whole number, but a real number is any existing number. An example of an integer is 6, -5, and 0. Any integer is also a real number, but a real number does not always have to be a integer. An example of a non real number is the square root of a negative number.

The set of integers includes the set of whole numbers and their opposites. 0, 1, -1, 2, -2, 3, -3, ...
They will never have decimal or fractional parts. They could be expressed as a fraction or a decimal such as 6 = 12/2 or 6.0, but there are no parts.
Real numbers is the set that contains all rational and irrational numbers. So they also contain integers, whole numbers and counting numbers.

An unreal or imaginary number is what you get when take the square root of a negative number.
An integer is a real number that whole and not a fraction.
in other words it goes -1,-2,-3, etc on to infinity plus 0,1,2,3,etc on to infinity.

A real number can be any fraction, irrational number, or integer, so integers are a subset of real numbers.

an interger is any positive or negative number that has no decimals. (for example -2, -1, 0, 1, 2, 3..etc.)
for lack of a better answer, a real number is any number that doesn't have an imaginary component (i = SR(-1) ). it is any number either positive or negative that either has a decimal piece or not.
