# Excel/excel formula 101

Question
Please tell me what this formula is doing with cell 15.
=+15/(sqrt(3))

the formula =+15/(sqrt(3)) (though the plus isn't needed nor the double brackets) is dividing 15 by the SQuareRooT of 3 (in other words = 15/1.732050808)

It's doing nothing with any cell contents though aas 15 is a number not a cell reference - if it was I5/sqrt(3) then it would be whatever is in I5 divided by the square root of 3
