Excel also allows you to refer to numbers on a different worksheet: e. g. =financials!d8, to duplicate the value from the financials sheet in cell d8 to your current cell. You can also use a more complex formula, e. g. =financials!d8*c7, to multiply d8 on financials with c7 from your current worksheet. The one place you could not use =d8, is in the cell d8 itself: there is no way to calculate the answer. Would occur if you used =d8 for cell c7, and the formula in d8. Follow the order of operations", when to priorities are tied, begin with calculation on left: bedmas = brackets, exponents, division, multiplication,
