Word Problems: Study Hall Algebra #2: ASU + Crash Course

We all know them, but we don’t all love them: the horrible Word Problem. Often, they seem like something designed just to trick or confuse us. But, actually, word problems fit right into how we need to look at math equations. They make us think about math visually and help us apply math to everyday situations.

Presented by Arizona State University and Crash Course, Study Hall is a tailored series of YouTube Learning Playlists aimed at helping you with resources to navigate college and your education path. Count on Study Hall to guide you to and through college.

Thank you to the sharp eyes that caught a typo. The solution at 6:25 should read 4800, not 480.

The popcorn problem blew my mind. It seems like the answer was in the back of my head and when you see it it's so obvious. Thanks a lot!

[Diana-wo]

I really like the popcorn and soda problem. No x's and no y's are needed, just pictures; I now approach a problem in a different way.

[bkbzgaming]

These concepts are good for foundation, not just college. I started learning this in 7th grade and these help me a lot!

[AT-pwdx]

Thanks so much for teaching us about our psychology when doing math problems. You have my respect

[ParadymShiftVegan]

These are truly incredible. Thanks so much for sharing! I can say confidently that these are the most insightful, relatable, and digestible math lessons I've ever had the pleasure of coming across. I hope to share these videos as much as possible 🙏🙏🙏 y'all deserve the exposure forreal

Is the fence problem not 4800m squared?? 80 times 60 not 480

[darelldoonyejiuwa]

Crash course is a very good channel first I didn't understand algebra now I do. Thanks a lot!

Awesome lecture I just had a suggestion for the first-word problem I believe it should be written like this; one gallon of 50% salt solution is mixed with 3 gallons each containing 10% salt solution. The way it is worded the 10% would have to be divided over the 3 gallons! So the concentration can have either equal or varying concentrations!

I so appreciate several things like recognizing the emotions and fun, yet Wow, this is still a BIG jump in complexity and unrelatability of the 1st equation! for people who have already had bad experiences and arent sure of what they can actually do. Love the 2nd equation, and am looking for others that are VERY easy to see patterns and math in real life situations. For homeschooling I'm going to have to skip the 1st example so they can relate. But thank you for this whole series!

after watching this I'm loving math thanks ASU

man that intro needs to be seen by all

5:36. Where does it say I need to use all 200 meters of fencing? Sounds wasteful. I'd just make the width 1 meter so the goat can fit and then the length is also just 1 m of the 200. The area becomes 1 and I've saved 197 meters of fencing for another project. PEDA approved. Gotta thank minecraft for this.

It's things like this in word problems where you're almost trained to make assumptions. I'm a swe, so breaking things where you don't expect them to is common. I've also learned you NEVER make assumptions; always clarify if there's missing details. You need to be more precise with wording. The classic "Can you get a bottle of milk from the store, and if there are eggs, can you get a dozen please?"

The husband returned with 12 bottles of milk.

For the problem where the farmer creates a pen for his goat, 80 meters multiplied by 60 meters is 4800 meters squared. Correct? the video states it as 480 meters squared.

I really like these videos!! Is this how all math is taught it ASU?

[joshbobst]

Years after thinking about this I realized it was an algebra problem: My Mack truck only goes 67 mph at its maximum rpm, because it's a vocational truck and has really low gears. The wheels have a 22 inch radius and the transmission output is .71:1 with the engine while in high gear. What ratio gearset do I need in the rear end to give 75 mph at 1700 rpm? Show your work. (Hint: each revolution of my 44 inch tall wheels will carry the truck forward 69 inches, or 79, 200 inches per minute at 75 mph.)

how many points do I need to get into Arizona state university

[Sunny-day]

0:22 I think the first thing you need to figure out is why you need so much fruit

[DerNesor]

Me at uni : How do I draw this space of homomorphisms ?

[murphygreen]

You have 200m of fencing, but do you have to use it all? If you make it 80x1 the goat can still fit and you've saved some fencing
