In Excel, the AND function is used to determine whether multiple conditions are valid at the same time, and its return result is TRUE or FALSE. 1. Basic usage: Return TRUE when all conditions are true, otherwise FALSE is returned, for example =AND(A1>10, A110, A1
In Excel, the AND function is a logical function that is used to determine whether multiple conditions are valid at the same time . If you need to judge that several conditions are "true", the AND function will come in handy.

Basic usage: determine whether multiple conditions are true
The syntax of AND functions is very simple:
=AND(condition 1, condition 2, condition 3, ...)
As long as all conditions are met (that is, they are TRUE), the function will return TRUE; as long as one condition is not met, the result is FALSE.

For example:
=AND(A1>10, A1<20)
This means determining whether the value of A1 is greater than 10 and less than 20. If A1 is 15, the result is TRUE; if A1 is 5 or 25, the result is FALSE.

Use in combination with IF: Return custom results based on multiple conditions
The result of using AND alone is TRUE or FALSE, which is not very intuitive. Usually we use it with IF functions to make the results clearer.
For example, when we want to show "Meet the criteria" when A1>10 and A1<20 is met, otherwise "Not met" is displayed:
=IF(AND(A1>10, A1<20), "Meet the conditions", "Not met")
This combination is very practical when dealing with data screening and conditional judgment.
Several common scenarios in practical applications
Determine whether the score is qualified : For example, both Chinese and mathematics must be greater than 60 points before passing the score
=IF(AND(Chinese score>=60, Mathematics score>=60), "pass", "failed")
Check whether the data is complete : For example, the three fields of name, phone number, and address cannot be empty
=IF(AND(A2<>"", B2<>"", C2<>"), "complete", "missing information")
Filter records that meet multiple conditions : for example, if a product has a inventory of more than 0 and the price is less than 100 yuan
=AND(Inventory>0, Price <100)
A few small details when using
- AND functions can accept up to 255 conditions, but don't write too much, otherwise the formula will become difficult to read.
- If a cell is empty, AND treats it as FALSE.
- You can combine other functions, such as OR and NOT, to make more complex logical judgments.
Basically that's it. Although AND functions are simple, they are very practical in actual work, especially when used with IF, which can greatly improve judgment efficiency.

To change the name in Microsoft Teams, take different steps based on the account type. For personal Microsoft accounts, you can go to account.microsoft.com to modify your name and sync it to Teams; for work or school accounts, the administrator needs to update it in the Microsoft 365 Admin Center; in addition, the display name can be temporarily changed before joining the meeting, but it will only take effect for the current meeting. All changes may take hours to sync and may be due to cache displaying old names in chat history or meeting playback.
