This document discusses various Excel formulas and functions for performing calculations on cell ranges. It covers simple formulas for addition, subtraction, multiplication and division of individual cells. It also demonstrates how to sum a range of cells using the SUM function, calculate the average of a range using the AVERAGE function, and find the minimum, maximum or count of values in a range using the MIN, MAX and COUNT functions respectively. The document shows how to define named ranges in Excel and use those ranges in formulas. It also discusses absolute cell referencing and using the formula bar view.

1. FORMULA AND
FUNCTIONS
By Piers

2. SIMPLE FORMULA
=A1+A2 Addition
=A1–A2 Subtraction
=A1*A2 Multiplication
=A1/A2 Division

3. ADDING SEVERAL CELLS…
= A2 + A3 + A4 + A5 + A6 + A7 + A8 + A9 + A10 +
A11
This is long! We can replace it with a function…
=SUM(A2:A11)

4. CAN YOU ANSWER THE…
questions?

5. ADDING SEVERAL CELLS…
What is the answer?
B4 B5 B6 B7 B8 Total
123 22 33 14 55

6. CALCULATING THE AVERAGE
D4 D5 D6 D7 D8 Formula
1 2 3 4 5 =(A1+A2+A3+A4+A
5)/5
We can replace this long formula with a function…
D4 D5 D6 D7 D8 Function
1 2 3 4 5 =Average(A1:A5)
What is the answer?

7. FINDING THE LOWEST NUMBER IN A
SEQUENCE
A1 A2 A3 A4 A5 Function
9 2 33 44 5 =Min(A1:A5)
Min is short for minimum
The lowest number in this sequence is….

8. FINDING THE HIGHEST NUMBER IN A
SEQUENCE
A1 A2 A3 A4 A5 Function
7 2 9 4 5 =Max(A1:A5)
Max is short for maximum
The highest number in this sequence is….

9. FINDING HOW MANY NUMBERS WE HAVE IN A
SEQUENCE
A1 A2 A3 A4 A5 Function
11 2 6 8 1 =Count(A1:A5)
What is the Count for this sequence?

10. FINDING HOW MANY NUMBERS AND TEXT WE HAVE IN A
SEQUENCE
A1 A2 A3 A
4
A5 Function
Apples 22 13 4 2 =CountA(A1:A5)
What is the CountA for this sequence?

11. ABSOLUTE CELL REFERENCES
Sometimes we do NOT want AUTOFILL to work.
So we must use an ABSOLUTE Cell reference…
To do this we must use DOLLAR signs
=$A$1+$A$2

12. QUESTIONS…
Put this formula into Cell C5: =$C3+$C4
Use Autofill for cells D5 to G5. What happens?

13. QUESTIONS…
Put this formula into Cell C5: =$C$3+C4
Use Autofill for cells D5 to G5. What happens?

14. QUESTIONS…
Put this formula into Cell C5: =C3+C4
Use Autofill for cells D5 to G5. What happens?

15. DEFINING RANGES
We can create a range for cells C3 to G3 called “Apples”
We can create a range for cells C4 to G4 called “Pears”

16. CAN YOU CREATE RANGES?
Create a range for cells C3 to G3 called “Apples”
Create a range for cells C4 to G4 called “Pears”

17. USING RANGES IN FORMULA…
1. What is the answer to this formula: =SUM(Apples)
2. What is the answer to this formula: =SUM(Pears)
3. What is the answer to this formula: =MIN(Apples)
4. What is the answer to this formula: =MAX(Pears)
5. Create a Range called “Fruit” for cells C3 to G4
6. Which formula will find the total fruit for the week?
