Answer 1

MATCH(lookup_value,lookup_array,match_type)

Lookup_value is the value you use to find the value you want in a table.

Lookup_value is the value you want to match in lookup_array. For example, when you look up someone's number in a telephone book, you are using the person's name as the lookup value, but the telephone number is the value you want.

Lookup_value can be a value (number, text, or logical value) or a cell reference to a number, text, or logical value.

Lookup_array is a contiguous range of cells containing possible lookup values. Lookup_array must be an array or an array reference.

Match_type is the number -1, 0, or 1. Match_type specifies how Microsoft Excel matches lookup_value with values in lookup_array.

If match_type is 1, MATCH finds the largest value that is less than or equal to lookup_value. Lookup_array must be placed in ascending order: ...-2, -1, 0, 1, 2, ..., A-Z, FALSE, TRUE.

If match_type is 0, MATCH finds the first value that is exactly equal to lookup_value. Lookup_array can be in any order.

If match_type is -1, MATCH finds the smallest value that is greater than or equal to lookup_value. Lookup_array must be placed in descending order: TRUE, FALSE, Z-A, ...2, 1, 0, -1, -2, ..., and so on.

If match_type is omitted, it is assumed to be 1.

Remarks

MATCH returns the position of the matched value within lookup_array, not the value itself. For example, MATCH("b",{"a","b","c"},0) returns 2, the relative position of "b" within the array {"a","b","c"}.
MATCH does not distinguish between uppercase and lowercase letters when matching text values.
If MATCH is unsuccessful in finding a match, it returns the #N/A error value.
If match_type is 0 and lookup_value is text, lookup_value can contain the wildcard characters asterisk (*) and question mark (?). An asterisk matches any sequence of characters; a question mark matches any single character.

in your example:

=if(MATCH(A1,B2:B100,0),
"Yes","No")

Match returns the index to the first item in B2:B100 that matches otherwise returns the #N/A result.

Answer 3

I'm not sure what you are trying to accomplish with this formula, but here is the correct format:

=if(A1=B1:B100,"Yes","No")

In order to receive a "Yes" answer, every cell from B1 to B100 would need to be the same as A1. If even one cell is different or blank, the answer will be "No"

Hope this helps.
