### Pete Crawley's Binary Numbers Presentation

1. 1. The Binary Number System<br />Peter Crawley<br />
2. 2. Don’t worry, by the end of class this will make sense.<br />
3. 3. Our number system<br />We operate on a base 10 number system (we don’t often refer to it as this because we use it all the time.<br />We have ten single digit numbers available to us<br />0,1,2,3,4,5,6,7,8,9<br />We can write all numbers in using a combination of these numerals<br />
4. 4. Counting<br />When we count from zero to 9 we can use our numerals<br />To go past 9 we need to begin combining our numbers<br />1 represents the number of tens we have<br />0 represents the number of ones we have<br />The result is 10<br />We go through our numerals until we need another ten, so we change the 1 to a 2 and reset the ones to 0 to get 20<br />This pattern continues until we need a new digit (the hundreds)<br />Think of 100 as one hundreds unit, zero tens unit and zero ones unit<br />
5. 5. The Binary System<br />The prefix bi means two (bicycle, bifold, etc.)<br />The binary system has two numerals (0 and 1)<br />The system works the same way as the base 10<br />0 means zero ones<br />1 means one one<br />We are now out of digits so we must add a new place, just like we added a new column for the tens, we now must add one for the twos (since there is no 2 in the system)<br />
6. 6. The Binary System<br />So the next number would be 10, or one two and zero ones (2 in our system)<br />Remember the saying “there are only 10 types of people in the world?”<br />The next would be 11, or one two and one ones (3 in our system)<br />We now must add a new place holder for the next number (the fours) and reset the others<br />100 would be 4 in our system (one four, zero twos and zero ones) <br />
