### Absolute Value

The value
that is created from the start point onwards is called

*absolute value*.
To
understand absolute value, let us start with a question.

The weather
in Istanbul is twice as warm as it is in London.

*If it is 0° C.*

*in London, what is the weather in Istanbul ?*

Is there not a mistake here? Whilst Istanbul is meant to
be warmer than London , the degrees are the same: 0°C

You can
give several different answers, such as 2 °C, -2°C, 1° C etc. however none of these
are correct. . It is unlikely that you can answer this question at this very moment because;

**Heat is an absolute value concept such as length and the start point is not 0 ° C .**
In other
words; twice the height of someone who is 1 metre is 2 metres but twice the value
of 5° C is not 10°C .

How come?

The start point for the length is 0 m. The child has a 1m magnitude of length from the start point and the basketball player has a 2m value from the start point.

## Heat as absolute value:

*The start point has been accepted as zero by International Standards. Absolute zero*

*is the lowest heat, and this degree is 0K – Kelvin – so 273 degrees. It is impossible to*

*lower the heat more than this, as there is no heat left within an object. Absolute zero*

*is where the vibration of molecules is nearly stopped and there is no movement. Due*

*to the vibrations it is called zero energy point and energy cannot be separated from*

*matter.*

Let’s turn back to the result of our problem;

Absolute value is formed by starting from the absolute minimum, for example, even if you owe someone or someone owes you $50. The transferred money, the value is $50.

When we talk about the distance between the two cities we are talking about the absolute value. We say that the distance between Istanbul and Ankara is "600 km" not "- 600 km". There

is no difference between measuring the distance from Ankara to Istanbul or Istanbul to Ankara.

*In conclusion, it is the value from the start point to the end point.*

## Absolute Value of Numbers

*"The distance from a number from 0 is its absolute value. "*

The absolute number is written between the symbols you see below.

**| |**

For example, the absolute value of 5 is written as such: | 5 |

\( \displaystyle \mid 5\mid =5 \)

For example ;

\( \displaystyle \mid -3\mid \)

\( \displaystyle \mid -3\mid =3 \)

What does this mean and what is its value?

The value from 2 to 6 or 6 to 2 is 4 units.
