Oracle recommends dividing complex calculations into components and combining the components into a compound calculation.
Example: To set up a calculation for (A + B) / (C x 2), where A, B, and C are members, you divide the formula into steps:
Set up Sum for A + B, and name it Step 1.
Set up Multiply for C x 2, and name it Step 2.
Set up Divide for Step 1 result divided by Step 2 result, and name it Step 3.
Use Show Only Members to hide Step 1 and Step 2. If you want to switch between seeing only members, seeing only calculations, and seeing both, you can use the Hide option in your document right-click menu.
