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!
