B fixed but allows the row reference to change - ANSWER-
Using a $ sign before both the row and column labels (for example, $B$4) keeps the

, Concatenation - ANSWER-•To concatenate means to join. In many applications, you
might wish to take text data that are in different columns and join them together (for

text30) can be used to join up to 30 text strings into a single string.

John. Then CONCATENATE(B1, " ", A1) will result in the text string John Smith.
Error Values - ANSWER-•#DIV/0!—A formula is trying to divide by zero.

SQRT.
•#REF!—A formula contains an invalid cell reference.
•#VALUE!—Excel cannot compute a function because of an invalid argument.
IFERROR Function - ANSWER-•IFERROR(value, value_if_error) displays a specific
value if an error is present.
•For example, if you are computing A1/B1, then if B1 is zero or blank, then
= IFERROR(A1/B1, " ")
will display a blank cell instead of #DIV/0!;
