In everyday life, many occasions contribute to the mental work of knowledge and meaning associated with a number. Although numbers have been a part of our lives, they are in some situations that have little to do with mathematics. From the pin code of phone to home address, from our age to the model of the car, they always present numbers. The numbers that help us understand mathematics can sometimes be thought of distinctly from mathematics. When you think of the number seven, for instance, you can ask why everything is so much related to 7.
