This specific step when factoring by grouping was a core memory of mine in high school math where I just memorized what to do and didn't understand what was happening. Here's how we can make sense of it. What did you memorize in math but didn't understand?

Hey Howie. This makes it make a lot more sense. Do u have a video explaining how to come up with the two middle terms? What I was taught was the diamond where the top is product of ax^2 times c and bottom is bx so the two middle terms multiply to top and add to bottom. Only way?

For whatever reason this made sense to me when it was explained; I might’ve had a good teacher tho

While I already did know the reason, due to it being a use of the distributive property (which I didn't consider that reason until after high school too), but the series of progressing apple examples is a brilliant way to teach this to students. Thanks for sharing.

I had a lot of trouble explaining factoring by grouping until someone told me to use the area model! 😀

Or you could say the share a factor of (x+4) so you factored it out. Just like the other terms shared “Apple”

Speaking of remembering an algorithm with no basis in understanding why... I learned this about 40 years ago...

Where's the explainer for why the 11x became 8x+3x? :>)

In high school math, I often memorized a procedure without understanding what was happening. Here's one specific step in factor by grouping that I didn't really understand until I became a teacher.

In high school, I didn't realize we could actually use difference of two squares to help us with mental math. Here's how we can apply this.

Whoopi: I keep laughing because I think you don't recognize excellence and creativity when you see it. Do you know how creative that was? What he did. Alyssa: The production alone. Unbelievable. Whoopi: I mean, come on, man. He [Trump] was upset. He said no one would understand what was being said. You didn't understand. A lot of people didn't. Sunny: You didn't have to understand or speak Spanish to feel the joy, the unity, and the message of inclusivity that was there. 🤣🤣🤣 How are these nutballs still on the air?

My high school math teacher was the first person who helped me realize I liked math and was pretty good at it. That’s what public schools do. But Trump’s voucher program will drain them of the resources they need. I’m fighting for every kid to have what I had.

Common Core math was introduced in 2010 to address standards across the U.S. and shift the focus from rote memorization to a deeper, conceptual understanding of mathematics. By 2026, it remains a common standard in many states, aiming to prepare students for college and the modern workforce by fostering critical thinking and number sense rather than just memorizing formulas. There has been much debate on using common core math in schools curriculum. Do you agree with using common core math in schools? Or do you think the old way of doing math was the better way to teach math to children?

Where was Tim Walz when it came to protecting this church that was targeted by these radicals? Did he call the pastor? Did he offer any help? Did he ask other churches what we can do to make sure their sanctuary is safe? I have a real suspicion he didn't make any of those calls. He’s probably fully in support of people like Don Lemon.

October 7th was the start of something that changed the trajectory of an entire generation, and I watched it unfold as just a senior in high school. This is what it means to come of age while a genocide was livestreamed and normalized while world leaders sent weapons instead of aid. I was radicalized by watching children in Gaza get bombed while American politicians clapped for it. The silence was complicity. And we’ll never unsee what they tried to keep buried. This time we weren’t too young to understand what was happening in front of our faces…understood enough to never be able to forgive them for it.

If Trump does manage to bring manufacturing back to America, he’s going to run into another problem, says “Dirty Jobs” host Mike Rowe: a lack of skilled labor in those trades. "On a broad level, we have to understand what we did to incite this. We took shop class out of high school. …And what we did when we took it out was not just shortchange that cohort of kids who might have seen something in the vocational world that made sense to their brain. What we did was we removed those jobs from sight for everybody." The Real Mike Rowe

Elon Musk's mother, Maye Musk, was a science nerd in school: “I was the science nerd at high school. I didn't really get many dates. I don't know if boys were scared of me or whatever, but I didn't have many dates, so I wouldn't date anybody who wasn't as good at math and science as I was, and no one was. Although my ex-husband was. He was better than me at math and science, and I hate to admit that, but that probably did help towards Elon being a genius.”

My mom was once shown this clip and she said, “I couldn’t understand what you were saying, but I could tell it was funny based on how you said it.” I told her, “It’s about how I told you I was a girl and you didn’t understand what I was saying” and we both laughed❤️ RIP, Mom ❤️

Cindy and Bryan Muehlberger considered moving, but didn’t know how they could leave behind the bedroom of their daughter, Gracie, who was killed in a school shooting six years ago. “We didn't want to leave that room,” says Bryan. “Do you take a lot of pictures of it and then try to recreate it somewhere else? We didn't know what to do with it.”
