Hey, Sal Hello, Brit I picked this up at a garage sale and I know you like colours. I love colours! You wear colourful shirts everyday and I thought you might like this. I do. This is very kind. I like it, yeah. So what are you hoping to do with this thing? Well at minimum maybe just represent numbers. Like counts? Keep track of numbers? Yeah you know counting the number of days or? 1, 2, 3. Yeah I could imagine doing that. Oh ok. So moving the bead down is a number, great. And that there's, there's 10. 10 there, so maybe that'd be 20, 30, 40, 50, 60, 70, 80, 90, 100. Yeah you could count 100 beads to keep track of things. What if I need to count to 105 or 6? Do I need to buy another one? I don't even know where to get more than these. Um, that would be an option. I guess maybe that's not an option if you don't know where to get it. Let's see. Um. Well, you know the different colours, you know, just like we have different forms of currency. Maybe we can have each of these, each of these colours or maybe the columns they represent a different amount. So this is 10 right over here. But what if we had one of these red beads represent 10 of these blue beads on this first column. So then you could go, this would be 10. Or you could say that is 10? So there's two representations of 10 here. On, yeah the way we just worked it out here, yeah. Okay. And then 11 would be that. Okay, and this is 21. Yeah, you have two 10s and a 1. The wooden colour or whatever colour. The skintone bead is going to represent all of the red beads. Yeah if each of one of these. Yeah that's a good system. If each column represents 10 of the beads to the column to its right that could be interesting. Because if this represents 10 red beads. That's ten 10s That'd be equivalent, this is equivalent to 100 blue beads. Wow. This would be equivalent to 10 of the brown beads. Which would be 100 of the red beads. Which would be 1,000 of the blue beads. And this would be 10,000 of the blue beads. And this would be 100,000 of the other blue beads. This would be 1,000,000 of the blue beads. And we're going to be able to repesent all the numbers in between? 1 and say 1,000,000? I think we can. Let me just give you a number and see how you do. What about 15,003? So let's think a little bit about this. So let's try the big numbers first. So see each of these is 1 and each of these is 10. Each of these is 100. Each of these is 1,000. I don't have 15 of these. But these are 10,000. Each of these are 10,000 So this is one 10,000 And then I could do 5 thousands. 1, 2, 3, 4, 5. So this is 15 thousand. So 1 ten thousand, 5 thousands. Then 0 hundreds, 0 tens, and then throw a 3 there. So 15,003.
