The only negative (although it is difficult to call it a minus) of this online calculator is that it does not know how to build spheres and other three-dimensional figures - only a plane.
How to work with the Math calculator
1. The display (calculator screen) displays the entered expression and the result of its calculation by ordinary symbols, as we write on paper. This field is intended just for viewing the current operation. The record is displayed on the display as you type a mathematical expression in the input line.
2. The input field of the expression is used to write the expression to be evaluated. Here it should be noted that the mathematical symbols used in computer programs do not always coincide with those that we usually use on paper. In the overview of each function of the calculator you will find the correct designation of the specific operation and examples of calculations in the calculator. On this page, below is a list of all possible operations in the calculator, also indicating their correct spelling.
3. The toolbar is the calculator buttons, which replace the manual input of mathematical symbols indicating the corresponding operation. Some buttons of the calculator (additional functions, the converter of quantities, the solution of matrices and equations, graphics) complete the taskbar with new fields, where data is entered for a specific calculation. The "History" field contains examples of writing mathematical expressions, as well as your last six entries.
Note that when you press the call buttons for additional functions, the value converter, matrix solutions and equations, plotting the entire calculator panel shifts up, closing the display part. Fill in the required fields and press "I" (the figure is highlighted in red) to see the display in full size.
4. The numeric keypad contains numbers and arithmetic signs. The "C" button deletes the entire entry in the entry field of the expression. To delete characters one at a time, use the arrow to the right of the input line.
Always try to close the brackets at the end of the expression. For most operations this is uncritical, the online calculator will calculate everything correctly. However, in some cases, errors are possible. For example, when the brackets are raised to fractional power, the denominator of the fraction in the exponent will go to the denominator of the base. The closing bracket is indicated in the display with a pale gray color, it needs to be closed when the recording is finished.
