When do I compare real-world numbers?

Mathematics

kumpel [21]3 years ago

The first aim of the numerations and numbers in general is to be able to compare things and to know what is bigger and what is smaller.
We compare numbers every day in our daily routine. For example: on the market, we compare the price of the products (the price of the apples for example refers to a real-world number). Or we compare the temperature during the day and during the night, which is also a real-world number.

A number is divided by 3. That quotient is increased by 12. The result is 46. Find the number.
anzhelika [568]

Let the number be x.

x/3 + 12 = 46

Subtract 12 from both sides and you will get:

x/3 = 34

Multiply both sides by 3:

x = 102

An entity with two multivalued attributes will be mapped as how many relations
grigory [225]
There are so many relationships between the original entity and new relation. 
The relation mapped from an entity involved in a 1:1 unary relationship contains a foreign key that correspond to its own primary key. 1 to one foreign key will be unique.
