Bellringer: Try these: • Determine what Excel formula would be used to solve the following problems. Write your answers in the spaces provided on your note sheet. • Assigns the sum of cells D4 and A2 to the active cell • Assigns the difference between cells P4 and G4 to the active cell
Excel Formulas Standards: 3.7.10CD-Apply basic computer operations and utilize software to solve specific problems 2.8.8F-Solve equations using computer spreadsheets
Formulas • Formula- the equations used to calculate values in a cell
Formulas • A formula consists of two components: • Operand- a number or cell reference used in formulas • Operator- tells excel what to do with the operands
Formulas • Example: In the following formula: =B3+5 • B3 and 5 are: operands • + is the: operator that tells Excel what to do with the operands
Formulas • Operator + • Operation addition • Example =B5+C5 • Meaning adds the values in B5 and C5
Formulas • Operator - • Operation subtraction • Example =C8-232 • Meaning subtracts 232 from the value in C8
Formulas • Operator * • Operation multiplication • Example =D4*D5 • Meaning multiplies the value in D4 by the value in D5
Formulas • Operator / • Operation division • Example =E6/4 • Meaning divides the value in E6 by 4
Formulas • Operator ^ • Operation exponentiation • Example =B3^3 • Meaning raises the value in B3 to the 3rd power…B3*B3*B3
Two methods for entering formulas • Key the numbers or cell references • Can be keyed in uppercase (A1), or lowercase (a1) • Point and click • Must end formula by pressing enter or any clicking will result in a change in the formula
Order of Operations • Order of operations- the sequence used to calculate the value of a formula • First- exponentiation (^) • Second- positive or negative (+ or -) • Third- multiplication or division (* or /) • Fourth- addition or subtraction (+ or -)
Copying Formulas • You can copy formulas by using: • Copy/Cut and paste • The Fill Handle • Can fill down or across
Relative, Absolute, and Mixed Cell Reference • Relative cell reference- adjusts to its new location when copied or moved • Example: • When in column A =a1+a2 • When copied to column B =b1+b2
Relative, Absolute, and Mixed Cell Reference • Absolute cell reference- does not change when moved or copied to a new cell • Example: • When in column A =$a$1+$a$2 • When copied to column B =$a$1+$a$2
Relative, Absolute, and Mixed Cell Reference • Mixed cell reference- $ before the row or column reference = they will not change when moved or copied; no $ = formulas will adjust relative to the cell to which they are copied • Example: • When in column A = $a$1+a2 • When copied to column B =$a$1+b2
Practice Determine what Excel formula would be used to solve the following problems. • 1. Assigns the sum of 12 and 9 to the active cell • 2. Assigns 6 times the contents of cell E22 to the active cell • 3. Assigns the product of 5 times the difference between the values in cells A1 and A2 • 4. Assigns the negative value of the product of the values contained in cells G7 and V67 to the active cell
