The answer, of course, is YES they can. In my perfect world of mathematics education, no pre_school child is ever exposed to a worksheet of any kind. I would swing my magic wand, all worksheets would disappear, and the memory of them would be gone forever. In the real world, I know that simply won't happen. There will still be some parents who will insist on using worksheets.
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.
