An integer is a whole number (not a fractional number) that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and 3,043.

An odd number is a number which is not divisible by 2. The remainder in the case of an odd number is always “1”. The property by which we classify an integer in math as even or odd is also known as parity.

`\xi=\lbrace1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16\rbrace`
`\begin{gathered} A=\lbrace1,3,5,7,9,11,13,15\rbrace \\ B=\lbrace3,6,9,12,15\rbrace \end{gathered}`

A)

`A\cap B=\lbrace3,9,15\rbrace`

B)
