Lesson 4 Excel Formula
Very Important!!
Excel Formula-Solve problem w/numbers
•Psychology
•Sociology
•Baseball Statistics
•Game analysis
•Accounting
Simple Formula Family
= A3 + b5
= A5*34
= C10/5
= D12 – b5
= $D$3-3
= $E$1/$d$1
Formula components1. =2. Operand:
b. 34,5,3 – numbers
3. Operator: +,*,/,-,^
a. C3,B5,D12 – Cell Reference
Order of Evaluation – Same Rule As Algebra -
( ) ^ - Exponent 2^2=4, 3^2=9
*, / +, -
To force the operation first
Let’s Practice
= ( A4 + B5 )*5 = A4 + B5 * 5
= A4 + B5 – 34 = A4 * A 5 / 34= A4/2 + 3= A4/(2+3)
3 Kinds of Cell Reference – You Need to Know …………………
1st Kind: Relative Cell Reference:
cell reference updated base on new location they copied & pasted to
3 2 =A1+B1 =B1+C15 3 =A2+B2 =B2+C26 4 =A3+B3 =B3+C39 4 =A4+B4 =B4+C41 2 =A5+B5 =B5+C52 8 =A6+B6 =B6+C6
2ND Kind of Cell Reference: Absolute Cell Reference
Absolute Reference: cell reference remain the same no matter where it is copied to.
3 2 =$A$1+$B$1 =$A$1+$B$1 =$A$1+$B$15 3 =$A$1+$B$16 4 =$A$1+$B$19 4 =$A$1+$B$11 2 =$A$1+$B$12 8 =$A$1+$B$1
3rd Kind: Mixed Cell Reference
Mixture of Absolute and Relative
= A3 + $B$4
= A$5 + $B5
To Sum Up…………….
Relative C1 Both the row and column will change when copied to another location
Mixed $C1 The column will not change when copied to another location, but the row will.
Mixed C$1 The row will not change when copied to another location, but the column will
Absolute $C$1 The column and row will not change when copied to another location
Here Comes the Review
Quiz 1
If you want to start writing formula by Excel, What symbol do you start with to tell Excel “ That’s a formula “ ?
= Equal Sign
Quiz 2 Name the order of evaluation
1. ( ) 2. ^ 3. *, /
4. +, -
Quiz 3 T/F
If you fill = A1 + B1 down from C1 to C2,the formula will remain unchanged
A B C D
1 3 4 =A1+B1
2 6 6 =A1+B1
3
Answer: False
Quiz 3 T/F If you want to make your cell reference
absolute, you need to add $ to your column letter and row number.
= $ A $4 + $B $ 5
OF COURSE! No Doubt!
Quiz 4 T/F
Relative Cell Reference: cell reference updated base on new location they copied to in the worksheet
Hope you get it right! Answer is YYYYYes!
