How to stop Excelcalculating threads

Whenever you change something on a Microsoft Excel 2010 spreadsheet, the program will recalculate some of the cells in the worksheet, even some of those that did not change. Normally, Excel operates fast enough that you won't notice the calculations taking place; however, if you have a large worksheet with hundreds or thousands of formulas, the constant recalculation can make the spreadsheet freeze for a moment every time you alter a cell. Although there's no magic button that will speed up calculations for every worksheet, you can do a few things to reduce your calculation time and make Excel run faster.
