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 KZbin 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.
Thanks to viewers like you, Study Hall has grown and moved from the ASU KZbin channel, where it launched in 2020, to its own channel. View your favorite videos and new ones at links.asu.edu/gostudyhallh1. We can’t wait to see you there!

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

[@suryakrit]

You're welcome.

[@tarunswami3130]

I was really unsure if I did the math right 😅

[@derekcook8358]

Yeah, I was just paused on that and decided to scroll down to see if there was an explanation. Thank goodness, thought I was loosing it. I've learned to follow along and attempt all problems presented before they are solved on screen, so that threw me.

[@brutalkangaroo30]

Lol saw and thought I was the one who was wrong !

[@DianaLikesToParty]

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.

[@arizonastateuniversity]

Glad you're finding the content valuable! You can find more videos on the Study Hall: Algebra playlist and subscribe for video updates at kzbin.info.

[@Kamila_Koziol]

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!

[@tarunswami3130]

Have u not studied linear equations with two variables?

[@bkbzgaming]

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

[@AT-pw9dx]

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

[@mikejarrell5531]

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

[@ParadymShiftVegan]

Correct

[@peggyproffit5479]

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!

[@fredleckie5880]

Thanks, really helpful

after watching this I'm loving math thanks ASU

[@justinblechinger3614]

man that intro needs to be seen by all

[@3rddimensionmedia950]

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!

[@BigCheese77]

Which doesn't change the solution though...

[@francisganapin4320]

good explanation

[@maryna.angelpa]

thank you

[@kiyotakaayanokoji2745]

Isn't it 4800 square meter

[@yitongliu9751]

That's what I think too.

[@adiongcasim3773]

It is 4,800 m²

[@Sunny-day8090]

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

[@joshbobst1629]

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.)

[@manishabais8702]

I think q2 is 4800 = 80 * 60

[@murphygreen8484]

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

[@GUY-jf3fz]

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

[@arizonastateuniversity]

If you're interested in becoming a future Sun Devil, check out admission.asu.edu.

[@krispybutter2555]

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.

[@MrManultra]

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

[@saralowry7318]

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

[@thruyaphone]

is there a playlist for precalc?

[@arizonastateuniversity]

At this time, there isn't a dedicated playlist for precalculus. Existing Study Hall content includes this series, English composition, data literacy and chemistry.

[@thruyaphone]

@@arizonastateuniversity oh okay thanks anyway :)

[@obeytweety]

I like how he shakes his chest slightly as he talks

[@suryakrit]

80×60 = 4800

[@yizuhi5908]

That's true

[@1co873]

Yeah, that's right

[@advickprosankto]

True dat

[@kuiper7002]

For the goat one i got 20m for the width…

[@kuiper7002]

Ohhhh nevermind i see my problem now, you were right, rereading the problem helps you with the problem you may be having!! Great series so far, i am looking to become a theoretical physicist but i must refresh my mind on math starting with simple algebra, everything has been really helpful so far and easy to take notes on! Great teacher/professor!

[@rob651]

I have one question though....what if one of your friends buys 3 sodas and 2 popcorns and pays $6, and also Another friend of you buys 2 sodas and 1 popcorn for $4. Then if you take one popcorn from each of your friends, how much will you pay them back?

[@yashikakathuria7654]

You would technically pay them back $0 since the popcorn itself costs $0, which doesn't seem very realistic price.

[@Bixittrue]

was anyone able to do the goat problem without watching the solution

[@katielooh4052]

Skip to 3:06 for the real problem

[@keeperofthelists4771]

Kay I'm just really dumb lol

That's okay, you can keep the lists for us 👈👈😎
