Office hours

OH are for everyone!Walking office hours are an experiment - come join!

I want everyone to succeed in this class!

We're going to cover a lot of ground, and it will be challenging,but you have what it takes!

If you're falling behind, change something!

Rarely does "working harder" solve the problem.

We'll evaluate your learning based on what you can do,not on a curve against each other.

A word on stereotypes

The digital abstraction

We handle complexity with abstraction.

And we enable abstractions by making restrictions.

The first fundamental one is the "digital abstraction"

By the end of class today, you should be able to:

Add numbers in binary

Write a positive decimal number in binary and vice-versa

Represent negative numbers using 2's complement

Decimal to binary (one of several ways)

If the number is odd, write a 1 and subtract 1 from the numberIf the number is even, write a 0Divide the number by 2 and repeat

To write a negative number in 2's complement:

Write the positive number in binary

Flip all the bits (1→0, 0→1)

Add 1 (with all the appropriate carries)

To convert negative 2's complement to decimal,

Flip all the bits (1→0, 0→1)

Add 1 (with all the appropriate carries)

Write the number in decimal

1. Read the book (1.5, 2.1-2.2) and complete the pre-class quiz

Quiz is due at 9AM the day of class, so I can review it
