When using a calculator for the first time, all the buttons and settings can be a little intimidating. However, the fundamentals of utilizing a scientific calculator are essentially the same as those of a regular calculator. When you understand the functions of the buttons and how to apply them to various computations, you'll be more than capable of utilizing your calculator both inside and outside of the classroom!
Learning Basic Functions
If there is a power button, locate it. Some of the more recent calculators feature a "ON" or "ON/OFF" button in addition to being solar powered, which means light activates them automatically. To turn the calculator on or off, locate and press any one of these power buttons.[1]
When your calculator is powered on, hit the "ON" button if your calculator has one to turn it off.
Certain calculators have an auto-off feature that activates after a short while of inactivity.
The "+" key is used to add integers. To add two numbers, use the "+" button between them. To add 5, for instance, press "5," "+," and finally "10."[2]
To a series, append more numbers. Press "+" and "5", for instance, to add to the total "5 + 10." Once you've determined the final solution, click the "=" button to obtain the sum of "20."
Use the "-" key to subtract numbers. To subtract a number from another number, press the "-" button in between the two numbers. To subtract 5 from 7, for instance, press "7," "-," and then "5". Then, press "=" to obtain the response "2."[3]
Take extra digits and subtract them from a series. To deduct from the total of "2 – 7," for instance, press "-" and "2." Then, press "=" to obtain the final result of "0."
After adding numbers, try subtracting them.
Using the "÷" or "/" key, divide numbers or convert fractions into decimals. To divide 2, for instance, press "2," "÷," and "1" before selecting "=." Press "4", "/," "5", and "=" to convert the fraction 4/5 to a decimal.[4]
The division key on a physical calculator is probably "÷." The division key on computer calculators is most likely "/."
To divide something into a series, hit "÷" or "/" and then a number. If your calculator displays "2 ÷ 1," for instance, press "÷," "2," and then "=" to obtain the final result of "1."
Utilizing the "x" or "*" key, multiply numbers. To multiply six by five, for instance, press "6," "x," "5," and finally "=." The final response will appear as "30."[5]
Computer calculators usually utilize "*" as a multiplication key, although physical calculators frequently use "x."
To perform a series multiplication, press "x" or "*" and then a number. In case your calculator displays "6 x 5," for instance, you can enter "x," "2," and "=" to obtain the ultimate result of "60."
To get the solution to an equation, press the "=" button. Hit "=" to obtain the final solution after entering the values in your equation and any necessary operations, like addition or subtraction. Press "10," "+," "10," and then "=", for instance, to obtain the final response of "20."
Always double-check your values first because you can only modify your equation with the ←/→ key after typing "=" and not erase anything else!
Press the "Clear" or "AC" button to empty the memory on your calculator. Press the "AC" or "Clear" button whenever you need to remove anything from the display and the calculator's memory. For instance, press "2," "x," "2," and then "=" to begin. "4", which is likewise kept in the memory, ought should appear on the screen at this point. The number will return to "0" when you press the "Clear" button.[6]
The button labeled "AC" indicates "All Clear."
If you press "+," "-," "x," or "/" after "4" and then attempt to enter a new equation without first pressing "Clear," the character will be incorporated into the equation that is now shown. In case you need to resume a calculation in the middle, always press "Clear".
