When working with the TI 84 Plus CE graphing calculator, you may come across situations where you need to find the absolute value of a number. The absolute value of a number is its distance from zero on the number line, regardless of its sign. Luckily, performing this calculation on the TI 84 Plus CE is a simple process. Here is a step-by-step guide on how to put absolute value in TI 84 Plus CE:
Step 1: Select the Number
Begin by entering the number for which you want to find the absolute value. This can be any real number, positive or negative.
Step 2: Access the Absolute Value Function
To find the absolute value of the number, press the “2nd” key on the calculator followed by the “0” key. This combination will give you access to the absolute value function.
Step 3: Enter the Number
After pressing the “2nd” and “0” keys, you will see a vertical bar symbol on the screen, representing the absolute value function. Enter the number you selected in Step 1 inside the parentheses following the vertical bar.
Step 4: Calculate the Absolute Value
Once you have entered the number inside the parentheses, press the “Enter” key on the calculator. The TI 84 Plus CE will then compute the absolute value of the number and display the result on the screen.
Step 5: Interpret the Result
The output on the screen will be the absolute value of the number you entered in Step 1. If the number was positive to begin with, the absolute value will be the same. If the number was negative, the absolute value will be its positive equivalent.
Practice Examples
For example, if you want to find the absolute value of -5, follow the steps outlined above. Enter “-5” after accessing the absolute value function and press “Enter” to get the result, which will be “5.”
Additional Tips
– Remember that the absolute value function on the TI 84 Plus CE is denoted by a vertical bar symbol “|” followed by the number inside parentheses.
– You can find the absolute value of variables or expressions by substituting them in place of numerical values in the function.
