Hey, fellow mathers! Welcome to the podcast where Math is Figure-Out-Able. I'm Pam Harris.

Kim  00:06

And I'm Kim Montague.

Pam  00:07

And this is a MathStratChat episode because we chat about our math strategies. Every Wednesday evening, I'll throw out a math problem on social media, and people from around the world chat about the strategies they use, and comment on each other's thinking.

Kim  00:20

Okay, so this week, the problem was 27 plus 99. We're curious how you will solve this problem. Pause the podcast. Solve it however you'd like. The problem is 27 plus 99. 

Pam  00:31

Dun dun dun.

Kim  00:32

Alright, I'm going to go first. 

Pam  00:33

Yep, go.

Kim  00:34

This one screams Over to me.

Pam  00:37

Screams! 

Kim  00:38

Screams Over 99.

Pam  00:39

Over! 

Kim  00:40

So, 27 plus 100 is 127. 

Pam  00:43

Over! Ah!! I'm screaming! 

Pam Harris  00:47

(unclear) 126. 

Pam  00:48

126. I'm sorry. I was kind of not really listening.

Kim  00:51

Totally fine. 

Pam  00:51

I was wondering how Craig's going to edit that out. Don't edit that out, Craig. Screaming! Ah! Okay, moving on. I'm going to think about this problem with 9s. 

Kim  01:00

Okay.

Pam  01:01

So, I'm thinking about three 9s is 27 and 99 is eleven 9s. So, three 9s and eleven 9s is fourteen 9s. And you might be like, "That's terrible, Pam," And I'm going to say, well, I can think about 9 times 14 like 10 times 14. That's 140. But then I have 1 too many, 14s, so I'm going to subtract 14. And 140 minus 14 is 126.

Kim  01:27

So, right now somebody's saying, "Okay, Kim's way was much better because it just got you the answer fast." And our argument is going to be because Pam strengthened her brain and used all kinds of great relationships. And that is the point. 

Pam  01:42

And it was interesting. Once I got to the 14 times 9, I had to think to myself what am I going to do? 

Kim  01:46

Yeah, yeah, yeah.

Pam  01:47

How am I going to think about 14 times nine? 

Kim  01:48

Yeah. 

Pam  01:49

Is there anything else? Like, would you Double and Halve from 14? Did you like my 10 times 14 minus 1 times 14? 

Kim  01:55

Yeah, for sure.

Pam  01:56

Nothing else comes to mind?

Kim  01:58

I mean, I think you could do Double Halve again. It doesn't get you tons nicer (unclear).

Pam  02:03

I don't think so. I think Doubling and Halving looks yucky.

Kim  02:05

7 times 18 is like 7 times 20. It's the same. It's it's going to lead you to the same Over though.

Pam  02:11

That's funny because I did the other way around. I got 28 times 4.5.

Kim  02:15

Oh. Yeah, that would not be as exciting.

Pam  02:18

Which, well, that's not... I mean 28 times 4.5, you could think about 28 times 5. Which is super. 28 times 10, cut it in half. You've already got the 5, which means you've got the 0.5. 

Kim  02:28

Mmhm.

Pam  02:29

So, that's actually not too bad. Ha! (unclear).

Kim  02:31

Very good. We can't wait to see what you all do every week. Join us on MathStratChat and let us know how you think about the problems. And share with other people! We need lots of people to join MathStratChat. Comment on each other's strategies. 

Pam  02:44

Yeah, the more you comment on strategies, the more people see MathStratChat, the more you share, then we can invite more people into knowing that Math is Figure-Out-Able, which is lovely. Ya'll, we post the problems on Wednesdays around 7:00 pm Central. When you answer, tag me, and use the hashtag MathStratChat, then join us to hear how we're thinking about the problem. We love having you as part of the Math is Figure-Out-Able movement because Math is Figure-Out-Able!
