Some calculators have a “Shift” key instead of a “2ND” key. In many cases, the color of the “Shift” or “2ND” key will match the color of the function’s text.
This is important when entering larger calculations, as leaving out a parenthesis can cause the equation to return a far different answer than you should have.
This is important when performing Trigonometry calculations. If you notice that your equations are returning decimal values instead of degrees (or vice versa), you’ll need to change this setting.

After completing a calculation, the last answer is automatically stored. You can perform another calculation on that answer by tying in the next operation. For example, if you just entered 2^4 and pressed ENTER (which equals 16), typing in -10 and pressing ENTER would subtract 10 from the solution (meaning it would be 16 - 10). Use the Answer function to recall the last displayed answer to an equation. When you press the Ans key, the last answer from the previous calculation will be added into your equation. Press STO after retrieving your preferred answer, press ALPHA, select a letter, and press ENTER. You can then use that letter as a placeholder for the answer you stored. [2] X Research source Some scientific calculators allow you to retrieve previous answers by pressing the up arrow button. When you find the answer you were looking for, press ENTER to place that number in your current equation. Note that there’s usually a limit to how many previous answers are stored, so you can only use this method for recent calculations.
You can also press the 2ND or Shift key and then press whichever button has “QUIT” listed over it (in most cases, this is the MODE key).

Find the square root (√) symbol. Either press the square root key or press the SHIFT or 2ND button and then press its key. Press 9 Press ENTER or = to solve the equation.
For example, to calculate 22, you would type in 2^2 and then press ENTER or =. To ensure the number order is correct, try performing a simple test, such as 23. If you get 8 as the answer, then you did it in the right order. If you got 9, then you actually did 32.

Perform a simple SIN function with an easy to remember answer. For example, the sine of 30° is 0. 5. On a scientific calculator, to find the sine of 30° for example, you type in 30, then sin get 0. 5. If you got a different answer, it probably means that your scientific calculator is not in degree mode. To put it in degree mode, look for a button that says DRG which stands for Degrees, Radians, and Gradients. If you push the DRG button several times, you will see that the mode in your view screen will change between degrees, radians, and gradients. Push the DRG button until you see degrees or DEG indicated in the view screen. Once you have degrees in the view screen, then type in 30 then SIN and you should get 0. 5.
Note how many parentheses are necessary to keep the formula intact. Proper parentheses use is essential to successfully using the calculator. Most calculators follow PEMDAS (parenthesis, exponent, multiplication, division, addition, subtraction), but using parentheses is the most sure way to correctly calculate the equation. After you’re done calculating for the day, you can try downloading games onto your calculator.
Press the MATH button. Use the up and down arrows to scroll up and down through a category of equations. Use the right and left arrows to scroll right and left through the different categories. Press ENTER or = to select an equation, then enter the number or formula to which you want to apply the equation. Press ENTER or = to calculate the whole equation.
You can check your calculator’s documentation to determine whether or not it supports graphing, or you can just look for the Y= button near the top of the calculator’s keypad.

For the X part of the equation, you’ll press the X,T,Θ,n key (or similar).
For the X part of the equation, you’ll press the X,T,Θ,n key (or similar).

You can view the graph’s individual points by pressing the TABLE (or Shift/2ND and then GRAPH) button and then scrolling through the resulting table. You can also use the graphing function to find minimum and maximum points on your curve.
You can press ZOOM to see a list of automatic zoom options. For example, ZoomFit will adjust the graph to show the entire curve.
