Math is Figure-Out-Able!
#MathStratChat - August 28, 2024
In today’s MathStratChat, Pam and Kim discuss the MathStratChat problem shared on social media on August 28, 2024.
Note: It’s more fun if you try to solve the problem, share it on social media, comment on others strategies, before you listen to Pam and Kim’s strategies.

Hey, fellow mathers! Welcome to the podcast where Math is Figure-Out-Able! I'm Pam.
Kim 00:07
And I'm Kim.
Pam 00:08
And this episode is a MathStratChat episode where we chat about our math strategies. Every Wednesday evening, I 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 00:21
Okay, so this Wednesday, our math problem was 176 minus 99. How would you solve this problem? Pause the podcast. Solve it however you'd like. The problem is 176 minus 99.
Pam 00:34
I'm going first. Pick Me. Pick Me.
Kim 00:35
Okay. You can go first.
Pam 00:39
Okay, 176 minus 100 is 76. But that's a bit too much. I subtracted too much, so I have to adjust by giving you 1 back. And so, I think the answer is 77.
Kim 00:54
Well, since you did my favorite strategy, I'm going to use one of your favorites. And you've always been better at this than me. I'm going to shift those numbers up by 1. And so, I'm going to make the equivalent problem 177 minus 100. And I also got 77.
Pam 01:16
Nice. We better pop in one more just for fun.
Kim 01:20
Okay.
Pam 01:20
I think 176 is sixteen 11s.
Kim 01:26
Okay.
Pam 01:26
And I think 99 is nine 11s. So, sixteen 11s minus nine 11s is seven 11s, which is 77.
Kim 01:37
Which is special to me because 7/11 of 77 is my husband's birthday
Pam 01:43
Aww. That's kind of fun.
Kim 01:45
Yeah, it's cool. Nicely done.
Pam 01:47
Nice.
Kim 01:47
Excellent. Okay, well, we can't wait to see what you do each week. Join us on MathStratChat and let us know how you think about the problems. And comment on each other's strategies while you're there.
Pam 01:57
We post the problems on Wednesdays around 7pm Central time. When you answer, tag me and use the hashtag MathStratChat, then join us here 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!
