Creating a Sum across worksheets. This is also an inter_active link. If a number changes on one worksheet, the sheet with the summary formula will also be updated. If a worksheet is inserted between worksheets in the sum, the sum will automatically be updated. Some of the disadvantages of this method are that all of the linked cells must be in the same location on all worksheets. Also, you can only sum one cell at a time (although you can copy the formula to other cells in the summary worksheet.) Using group mode to create identical spreadsheets will help when using the sum function across worksheets. This method is also limited to within a workbook and cannot be done across workbooks.
In 1986, mimeograph machines were (for the most part) replaced by digital copiers in elementary schools. Those of us teachers who experienced using mimeograph machines will forever remember the distinct smell of the still_damp, purple_ink worksheets that we handed out to our students _ by the ream full. (If you're like me, you can remember that smell right now!)
