**1.2 - Logic with Bits**

**How can a machine make decisions?**

When are the following statements * true* and when are they

*?*

**false**It is raining

**and**it is night time.It is snowing

**or**it is December.

Take the second statement above - "It is snowing * or* it is December". Is that statement true if it's December but

*not*snowing? What about if it is December

*and also snowing*?

Everyone should be complete Unit 0 Lessons 0.1, 0.2,

**and**0.3.From last class:

Binary is made of 1's and 0's that represent electricity being on (1) or off (0).

Computers use electricity and, therefore, can only work with binary.

We use bits (and "bytes") to represent

*any*kind of data: numbers, letters, media, encrypted messages, etc...

**Today's Lesson: 1.2 - Logic with Bits**

I have to admit, I wish I had called this lesson "Bits of Logic". Get it?

How do we control "bits" in a computer?

How do we do mathematics and make decisions in a computer with bits?

*will*have time in class tomorrow to continue working.

When you are finished and have submitted your assignment, you can attempt the bronze, silver, and gold challenges (also in Hapara)

**TONIGHT:**Complete independent lesson 0.4Yes, I'm aware 0.3 was on logic gates and 0.4 is on binary. Repetition is a key factor in learning new topics.

**Extra**

There's been a new challenge posted (C.00 - "Inspector Gadget")
