He was an English mathematician, educator, philosopher and 

logician

. He worked in the fields of differential equations and algebraic logic, and is best known as the author of 

The Laws of Thought

which contains Boolean algebra. Boolean logic is credited with laying the foundations for the information age.

George Boole

Nov, 2 1815 – Dec, 8 1864

Let’s Start Thinking in Boolean

1 = True

0= False

Boolean Logic - AND, OR, NOT

AND (conjunction), denoted

X

∧Y or sometimes X AND YThe Rule:

X∧Y = 1, If and only if X = 1 and Y = 1All other cases are 0

X

Y

Boolean Logic - AND, OR, NOT

OR (disjunction), denoted 

X

∨Y or sometimes X OR 

YThe Rule: X∨Y = 0, If and only if X = 0 and Y

 = 0All other cases are 1Introduction to Raspberry Pi and Kano

Boolean Logic - AND, OR, NOT

NOT (negation), denoted ¬

Conditions Result in Boolean Results

Logical statements are either True or False.

For a value of X and Y evaluate the following statements:

If X == Y = ?

If X < Y = ?If X > Y = ?If X >= Y = ?If X <= Y = ?If X != Y = ?What other conditions can we have?

Why do we need logic?

To control what a program will do and how it will do it.

What’s a Function?

In programming, a

named section

of a program that performs a specific task. In this sense, a function is a type of

procedure or routine.

Function Body

Return Statement

Return Value

Function Name

Function Arguments

What’s a Variable?

In computer programming, a

variable

or scalar

is a storage location paired with an associated symbolic name, which contains some known or unknown quantity of information referred to as a value.

Are you the same? – Equals Logic (==)
