Thanks Shiina! As a new clipper I sure picked a pretty difficult clip to start with...lmao. The subtitles we're challenging, but I'm glad you enjoyed it!
You can't expect school teachers to explain things they don't understand themselves. School math is presented as something hard and unnecessary, while in reality it's literally a cheat code.
Tricks to solve this: 1. The borrowing method is a stupid name for normal addition. You perform inverse addition to find 2988, but the cheat way is simple. Find the ones first, 8, then check the answers. If two have the same ones spot, check the tens, and so on, till you find the answer. 2. 2b + 3s = 2(2.5) + 3(2.8) = 5 + 8.4 = 13.4. Simple algebra. 3. This question is checking to see if you understand short hand stuff. In this case, what the in between measurements are on the measuring device. In this case, each dash is a 2. So A has 12, and B has 22. (12 + 22) / 2 = 34/2 = 17. 4. This one is tricky as only gamblers really use the x to y format for ratios. Most cook books dropped this as well. Anna gets 2 for every 3 Bernie gets. That means we need 5 candy to properly distribute. 25 is 5*5 so we distribute 5 times. 2*5 = 10, and 3*5 = 15. So Bernie has 5 more than Anna. 5. Fractional math. First get a common denominator, unless you know certain things prior. 5, 6, 10, 15 has 5, 2, 3, 5 so about 150. Yeah not doing that. 3/10 is less than 4/10 or 1/5. 5/6 is greater than 4/5. 7/15 is roughly 1/2. -5/6, -4/5, -7/15, -3/10, 3/10, 7/15, 4/5, 5/6 because -5/6, -4/5, -1/2, -1/4, 1/4, 1/2, 4/5, 5/6 6. Fractional math again. this time 20 candy, and a need to reduce the fraction. 12/8 or 2*2*3/2*2*2 = 3/2 7. Dad answer. This is a question to shut a bored kid up while driving. You pick the largest number which is D. These things carry tons of material.
Thank you for the clip! Love the clear subtitles you added so much 🥰

I love how so many of the problems were solved in such roundabout ways. But they were solved.
Just like the real deal tbh... no matter how mathematicians online make it look easier.
It'll never cease to amaze me every time I realize that the reason people struggle with math is because they're doing it the hard way.
which to be fair, school really didn't prepare us fully enough to systematically drill down the easy ways.
@@forgotultag1543Unfortunately, many schools didn’t teach math as puzzles to solve but as hurdles to jump. Undermining what’s fun of math.

I relate so heavy to Hina's "Im not even going to try this" method.
4:20 I had the same reaction; about half a second before Hina I yelled out "what??!?!"
Yeah I had the same reaction watching live lmao, it's much easier than they were making it seem - which is why I was confused and probably Hina too.
Imagine not passing highschool soley because of math. Couldn't be me
My god Hina is so freaking precious. We have similar mental math skills as well.
Chuubamathing oh just end me now 😵💫
I love how this clip just shows Hina as the personification of "no thoughts, head empty".
Yeah its a classic!
We should have seen this coming. On debut Hina thought lightyears where a measurement of time
Technically she is correct....but not in a way she's thinking ^_^;.
You can do it from the right too:
7000-4000=3000; 600-700= -100; 90-0=90; 1-3= -2
3000 -100 +90 -2 = 2988
This is useful with big numbers to get you in the right range quick without doing all the math.
2:40 What the hell is even going on here??

7/15 is roughly 1/2.
-5/6, -4/5, -7/15, -3/10, 3/10, 7/15, 4/5, 5/6 because -5/6, -4/5, -1/2, -1/4, 1/4, 1/2, 4/5, 5/6

Mathematically speaking, the freight tank question is unsolvable. There isn't enough info there.
There is. It is called parents or an adult who informed the kids prior.
@Ramanuj_Sarkar you can, but you're doing more work than you need
@@henriquepacheco7473 It's less math and more of a measure of your judgment/perception.
its ok hina i will do your math problems for you as your husband it is my duty.
It's not Hina's fault her brain is the size of a bird.
