2. Select formula (1) and then evaluate formula (2).
3. Click on Evaluate
Keep clicking "Evaluation" to evaluate all your formulas. This is in case you have multiple formulas like =SUM(A2:A6,B2:B5). A2 to A6 is one formula, and B2 to B5 is another. Repeating this click on evaluate will show the result of A2:A6, and B2:B5 respectively.
