How to Calculate Absolute Value on a TI-83 Plus or TI-84 Plus Calculator
Accessing the Absolute Value Function
Begin by pressing the [MATH] button on your TI-83 Plus or TI-84 Plus calculator. Then, use the arrow keys to scroll right to the NUM menu and select 1:abs( to open the absolute value function.
Inputting the Number
Type the number or equation for which you need the absolute value. If the number is negative, use the negative value key located below the [3] key.
Completing the Calculation
After entering your number, close the function by pressing the ) key found above the [8] on the keypad. Conclude the operation by pressing [ENTER]. The calculator will display the absolute value result on the screen immediately.
Practical Example
To find the absolute value of -3, simply input abs(-3) following the steps above and press [ENTER]. The calculator will show the result as 3.
Using this straightforward process, the TI-83 Plus and TI-84 Plus make calculating the absolute value quick and efficient for students and professionals alike.
How to Calculate Absolute Value on a Calculator
Calculating the absolute value on a TI-83 Plus or TI-84 Plus graphing calculator is a straightforward process. This guide will show you how to quickly determine the absolute of any number using the abs() function.
Accessing the Absolute Value Function
To begin the calculation, press the [MATH] button. This is the first essential step in accessing mathematical functions. Next, navigate to the 'NUM' menu by scrolling right. Here, you will select the first option 1:abs(, which stands for "absolute value."
Inputting the Number
Once you've opened the abs() function, input the number whose absolute value you need to find. If your number is negative, use the negative key [(-)] located just below the [3] key to enter it correctly.
Getting the Result
After entering your number, press [ENTER] to compute its absolute value. The calculator will display the result, showing you the absolute value of the inputted number.
By following these simple steps, you can efficiently perform absolute value calculations on your TI-83 Plus or TI-84 Plus calculator, making it a useful tool for math homework and tests.

Calculating Absolute Values on a Calculator
Learning how to compute the absolute value using a calculator can simplify solving mathematical problems that involve distance and magnitude. Below are step-by-step examples that utilize different calculator types.
Example 1: Basic Calculator
For calculators with an 'ABS' function: Input the number, press the ABS key, and the display will show its absolute value. For instance, for -8, press ABS to get 8.
Example 2: Scientific Calculator
Scientific calculators allow for more complex functions. To find the absolute value, input the number and then press the |x| key. Enter -15 and hit |x| to receive 15.
Example 3: Graphing Calculator
Graphing calculators typically involve a sequence. Enter the number, access the 'MATH' menu, select the 'NUM' submenu, find 'abs()', and press 'Enter'. Using number -23, the result would be 23.
Example 4: Calculator App
Most smartphone calculator apps support absolute value. Locate and select the 'abs()' function, input your number, and confirm. For -34, the output on a typical app would be 34.
By understanding these methods, you can quickly compute absolute values, essential for algebra, analysis, and practical applications.
