Once you know what you need, the next step is to determine your budget. On the other hand, if you're a professional engineer or scientist, you may need a calculator with even more advanced features, such as the ability to solve equations or plot graphs. For example, if you're a student, you may want a calculator that can handle basic math operations, as well as more advanced functions like trigonometry and logarithms. Different calculators have different features and capabilities, so it's important to find one that meets your specific needs. The first step in choosing a scientific calculator is to consider what you'll be using it for. In this article, we'll provide some tips to help you make an informed decision. But with so many options on the market, it can be overwhelming to choose the right scientific calculator for your needs. These calculators are designed to handle complex mathematical operations and offer a variety of functions that can make your work easier and more efficient. Though it is possible to use arithmometer for addition or subtraction, it is quite difficult to do.īased on its working principle, the predecessor of a calculator is a digital device, that is why the result of calculation is always one hundred percent correct.If you're a student or professional in a science-related field, you'll likely need a scientific calculator at some point. It was primary used for multiplication and division. The direct predecessor of a calculator is a mechanic and portable counting machine called arithmometer. Subtracting a percentage from a number: 500 25. The result is equal to 5(%).Īdding a percentage to a number: 500 25. The result is equal to 125.Ĭalculating what percent is one number of another number: 25 500. The result is equal to 81.Ĭalculating a percentage of a number: 500 25. The result is 3.Ĭalculating the square root of 529: 529. The logarithm of 125 to the base 5: 125 5. You can use the and keys on top of the keyboard, or the key on the side numeric keypad to reset the calculator.Įxamples of calculations performed using the online calculator Use the key on the side numeric keypad to enter the division sign. Use the key on the side numeric keypad to enter the multiplication sign. To enter a minus sign, use the key at the top or on the side numeric keypad. ![]() To enter a plus sign, use the key at the top or on the side numeric keypad. To delete the last character, press the (arrow) key. You can use the key to enter the equal character. The calculator supports input from any numeric keys of a computer keyboard: both the numeric keys on the top and the separate numeric keypad on the right. resets the calculator without resetting the memory.Įntering commands using a computer keyboard reset the calculator and reset the memory saves the number to memory with the sign addition, - subtraction, - multiplication, - division changes the mathematical sign of the displayed number to the opposite one deletes the last character entered on the display is the natural logarithm (to the base e) is a mathematical constant, Euler’s number ![]() is a mathematical constant, the ratio of a circle’s circumference to its diameter How to work with a scientific calculator Calculator keys to perform trigonometric functions Moreover, you can customize the settings of the calculator and save them.īelow you can find examples and information on how to use a scientific calculator. Using this calculator, you can find the logarithm of a number, raise to a power, find a root square and, moreover, a nth root.Ī scientific calculator is easy to use online-there is no need to download or install it on your PC or laptop.įor any calculation, you can use either mouse or numpad. A scientific calculator supports calculations of trigonometric functions, such as sine, cosine, tangent, cotangent, etc.
