1. How do I enter text into a cell in a spreadsheet? 2. What are the two formats for numbers? What is the difference between them? 3. Formulate the rules for writing formulas. What happens if you break these rules when you enter a formula? How can you prepare a table for calculations in advance?

1. In order to enter text data into a cell of a spreadsheet, select it with the left mouse button. This cell will appear with a bold outline, and then you can enter data into it. When you have finished entering, you can press the Enter key.
2. In numerical and exponential. Numeric allows you to determine the number of decimal places, exponential represents the number in standard form. When entering in exponential form, it is enough to enter the mantisa and after entering “e” enter the power of the number.
3. The data that goes into the cell is reflected automatically in the formula bar. Sometimes it is convenient to enter directly into the formula bar. Formula entry always begins with an = sign. If this is not done, then the formula is perceived as text.
4. It is not at all necessary when creating a spreadsheet to enter the initial data into it right away. The table can be prepared in advance for calculations in the form of a table layout that is not filled with numbers. To do this, you first need to fill in all the cells with the appropriate formulas and enter text information.
