# Order of Operation Example TI84

JoeStat’s want you to calculate the following equation. #### Order of Operations

Highest Parenthesis Brackets
High Exponents Roots
Low Multiplication Division

#### Hint:  Solving the equation using a (TI83, TI84, TI89) calculator:  First convert the equation into something easy to enter into the calculator.
Original: Step 1: Reformat fractions to one line Step 2: Reformat Radicals with parenthesis and brackets Step 3: Entering the equation into the calculator

• | [ ( ] | [ (-) ] | [ 9 ] |
• | [2nd] | [X^2] | [ 4 ] | [ + ] | [ 3 ] | [ ^ ] | [ 2 ] | [ ) ] |
• | [  / ] | [ ( ] | [ 1 ] | [ 5 ] | [ – ] | [ ( ] | [ 3 ] | [ + ] | [ 2] | [ ) ] | [ * ] | [ 5 ] | [ ) ] |

Solution: Solving the equation by hand: Step 1: If you have problems dealing with fractions, or have already input the solution to into a calculator reformat it to: Step 2:

1. 2. 3. 1.  If you have problems dealing with fractions, or have already input the solution to into a calculator reformat it to: 2. Calculate the inner-most nested parenthesis   3. Calculate net inner-most nested parenthesis  4. Calculate next inner-most nested parenthesis   5. Calculate next inner-most nexted parenthesis  6. Finish the problem
