Transcript

  • 1. Building Formulas With Excel COMPUTER LITERACY FORM 1
  • 2. Formula
    • A formula is the written expression of a calculation to be performed by Excel.
  • 3.
    • When you enter a formula into a cell, the formula is stored internally while the calculated result appears in the cell.
  • 4.
    • To allow Excel to distinguish formulas from data, all formulas begin with an equal sign ( = ) or a plus sign (+).
  • 5.
    • The following are
    • mathematical operators in a
    • excel formula.
  • 6. Subtraction - Addition + Division / Multiplication * Exponentiation ^ Meaning Operator
  • 7.
    • When a formula contains two or more operators, the order in which operations are performed is determined by operator priority.
  • 8.
    • For example, exponentiation is always performed before any other operation.
  • 9.
    • Multiplication and division are next on the priority list, performed sequentially from left to right.
  • 10.
    • Finally, addition and subtraction are performed, again from left to right. Consider the following equation.
  • 11.
    • 2 + 4 * 6 / 3 - 1 = 9
    • First, four is multiplied by six,
    • and the result is divided by
    • three. Two is then added to
    • the result, and one is
    • subtracted.
  • 12.
    • Operations contained within parentheses are completed before those outside parentheses.
  • 13.
    • Thus, the following equation is calculated differently than the previous one.
    • (2 + 4) * 6 / (3 - 1) = 18
