I am sure that this question has been asked and answered. I am creating a
worksheet for my class. I have a value in cell b2( I want use this value
thru out the sheet). Let say b2 = 10

b c d
3 5 6 8
4 3 7 1

I want to subtract each value from b2(10). How can I do this without doing
it manually?

Does that mean that you want the following end result
(if not, explain what result you do expect).

b c d
3 5 4 2
4 7 3 9

This may be accomplished by the following command sequence

Put -1 in any spare cell, say F10
Select cell F10 (that has the value -1)
Copy
Select cells B3:D4
Paste Special - Operation = Multiply
Select cell B2 (that has the value 10)
Copy
Select cells B3:D4
Paste Special - Operation = Add
Clear cell F10 (the spare cell)

Hope this helps / Lars-Åke
