What is Absolute Value?

The absolute value of a number is its distance from zero on the number line, without considering direction. It's always a non-negative number. For any real number a, the absolute value is denoted as |a|.

How to Put Absolute Value Into Calculator

Most scientific and graphing calculators have a built-in absolute value function. Here's how to use it:

1. Turn on your calculator and clear any previous calculations.
2. Enter the number for which you want to find the absolute value.
3. Locate the absolute value function. On most calculators, this is represented by the "abs" key or the vertical bars (| |) around the number.
4. Press the absolute value function key or enter the vertical bars.
5. Press the equal sign (=) to calculate the result.

Absolute Value Formula

The absolute value of a number a can be expressed mathematically as:

This formula shows that the absolute value of a positive number is the number itself, while the absolute value of a negative number is its positive counterpart.

Absolute Value Examples

Let's look at some examples to understand how absolute value works:

• |7| = 7
• |-3.5| = 3.5
• |0| = 0
• |-√2| = √2 ≈ 1.414

These examples demonstrate that absolute value always returns a non-negative result, regardless of the input's sign.

Absolute Value in Real Life

Absolute value has practical applications in various fields:

• Finance: Calculating the difference between two values without considering direction (e.g., profit or loss).
• Physics: Determining the magnitude of displacement or velocity.
• Engineering: Measuring distances or tolerances in designs.
• Everyday Life: Comparing quantities like temperature differences or price changes.

Understanding absolute value helps in making accurate comparisons and calculations in these real-world scenarios.
