The AND formula in Excel is a logical function used to check if all conditions in a set of arguments are TRUE. It returns TRUE if all conditions are met, otherwise, it returns FALSE.

Syntax:
=AND(logical1, [logical2], ...)

• logical1: The first condition to evaluate (required).
• logical2: Additional conditions to evaluate (optional).

Example:
Suppose you want to check if a student has passed both Math and Science exams (score >= 60). You can use the AND formula as follows:
=AND(A2>=60, B2>=60)

• If A2 (Math score) is 70 and B2 (Science score) is 65, the formula returns TRUE.
• If A2 is 50 and B2 is 70, the formula returns FALSE.

Tips:

1. You can use up to 255 conditions in the AND formula.
2. Combine AND with other functions like IF for more complex logic.
3. Blank cells or text values in logical arguments are ignored.

Common Errors:

• If all arguments are FALSE, the formula returns FALSE.
• If any argument is an error, the formula returns an error.
