Key ideas in Working with Excel

  • Typing an equals sign (=) first tells Excel to switch from passive text entry into calculation mode
  • Typing numbers and math symbols without a leading equals sign causes Excel to treat the entry as plain static text
  • The formula bar displays the true raw number or formula stored inside the active cell
  • A cell's visible display can be rounded or formatted with symbols while its true underlying value remains unchanged
  • Excel performs calculations using the cell's underlying value rather than its visible formatted text
  • Excel recognizes standard calendar sequences like months or days of the week from a single starting cell
  • Dragging a single plain number repeats that same number rather than incrementing it
  • Selecting two numbers establishes a mathematical interval that Excel continues down the column
  • Clicking AutoSum detects adjacent blocks of numbers directly above or to the left of the active cell
  • AutoSum automatically constructs the =SUM() formula and displays a marquee outline around the guessed range
  • Pressing Enter confirms the AutoSum proposal and displays the sum in the selected cell
  • Pressing Escape while editing a cell cancels all in-progress changes and restores its previous content
  • Pressing Enter or Tab commits whatever accidental changes were typed into the cell
  • Typing cell coordinates like A1 and B1 links Excel to the live contents of those cells
  • Entering hardcoded numbers like 40*25 freezes the calculation, requiring manual edits whenever values change
  • Formulas in Excel must always begin with an equals sign (=) to calculate instead of showing plain text
