Addition of Binary Numbers
This lesson teaches how to add two or three-digit binary numbers. It covers the basic rules of binary addition, including carrying over when the sum exceeds one. Several examples are provided to illustrate the process.
- 02:30 “one, zero, one, one, one, one, one, so we have one, zero, one, one, one, one, one, one, one, one plus one is one and zero plus one, this, right one, take one to the next column, one plus one is what, ten, that's one and...”
- 03:15 “So we have, we have done this one plus one, this is one and zero, plus one, this, plus one. How do you do this? One plus one is ten already, then take one here, one plus one and under what, another ten. So we have it on...”
- 01:37 “give you one and zero. Write this one, then take the other one, carry the other one to the other side of the next column, one plus one, we give you ten, sixty, one and zero, the right one, then take one to the next colum...”
Counting in Binary
This lesson teaches how to count using the binary system, which uses only the digits zero and one. Students will learn to represent numbers in base two and understand the place values associated with binary digits. Activities include grouping counters to illustrate binary numbers.
- 07:12 “Use the method in example one to represent the numbers from one to twenty in base two in a paper abacus. So for each number, you're going to do this. Group them into eight, four, two, and one. We have done number nine fo...”
- 05:40 “So what next are we asked to do? So we asked to represent this on a paper abacus. So on a paper abacus, let's draw abacus. A paper abacus. Let's draw a paper abacus. Um, we have eight, eight, we have fours, then we have...”
- 00:59 “which is known as a decimal system. We have digit zero, one, two, three, four, five, six, seven, eight, and nine. We use this digit to represent numbers in base 10. The binary system is the second in importance to our us...”
