If you have recently purchased a Texas Instrument calculator called the TI-30X IIS, you may be feeling overwhelmed with learning how to use it. Learn the basics for computing basic addition, subtraction, division, and multiplication before moving on to more complex calculations, such as exponential equations. Show your child how to use the calculator by trying equations together. You can then test your child's knowledge by giving her random formulas and equations to try out on her own.

#### Step

Turn on your calculator using the "On" button at the bottom left corner of the calculator.

#### Step

Type a basic equation, much as you would using a standard calculator. A scientific calculator is different from a standard calculator because it can calculate several operations -- such as subtraction and multiplication -- in the correct order. Type a basic equation such as the following:

## Video of the Day

5 + 6 - 2

Press "Enter," which also is the "=" button located at the bottom right corner of the calculator.

#### Step

Input an arithmetic expression such as the following:

12 x (10+4)

To insert parentheses, press the individual parenthesis button just above the "8" and "9" buttons. Press "Enter."

#### Step

Calculate exponents by typing your base number, such as "10." Then press the exponent symbol number, which is the "^" symbol and is the fourth button above the "On" button.

#### Step

Insert negative numbers by pressing the negative symbol button, which looks like "(-)" and is located below the "3" button. Type your base number.

#### Step

Turn off your calculator by pressing the "On" button.
