[@miguelterrazas7595]

Grammar hero, thanks to you I went from a 28 to a 62! Got my dream job and I ship out the 20th of May!

[@GrammarHero]

Congrats on more than doubling your score, you're welcome, and I wish you the best in the military! If you don't mind me asking, what branch did you join?

[@manonfire3339]

Congrats, sir!!! I wish you the best. Everytime I read comments like these I get hope that it can happen. And thanks to Grammar Hero I can see it happen. I have learned things I never though I'd be able to understand.

[@JjPoncho-ze6dx]

Dude this makes me tear up I’m dreaming of joining the navy with shoulder surgery I want to pass the ASVAB with a high score in order to get a good job . Hope you’re doing well

[@batoolhayat3393]

😢so happy for you

[@ialexbabb]

Hey man! just want to say thanks you for this channel. I’ve learned more about math in a few months than my 12 years in school. I passed my asvab and swore in yesterday ✅ keep hammering away my good sir ⚓️

[@abbieamavi]

I almost have my college degree in a science field and have never had anyone explain it this well to me. Thank you!!

[@sueviettenunghues]

This is the first time I know what prime number is, actually my Vietnamese Math teacher teach me before but all of them talk too much and I still confused and never understand, you help me grammar hero T-T

[@eazyshooter6611]

Very helpful glad i found your videos taking the asvab monday wish me luck...

[@GrammarHero]

Good luck!

Taking ASVAB tomorrow, watching this video to review. Wish me luck!!!

Good luck!

this video was helpful thank you I take the ASVAB in 2 days I've been studying your videos for the pass few weeks. I hope I pass it this time

I needed this one. Thanks for the heads up! Good looking out for me again! I should be headed to MEPS in the first week of April. I’ll let you know how I do on the ASVAB.

[@GrammarHero]

Is 1344 a prime number?

[@drewhighfill9253]

@@GrammarHero Lordy, that’s a good one. Give me a few minutes to work this out.

[@drewhighfill9253]

@@GrammarHero It is not a prime number. It can be divisible by 2. 2 and 672 = 1344

[@drewhighfill9253]

@@GrammarHero it can also be divisive by 3. Because you can break down 672 to 3 and 224. Then 4. 226 is broken down to 4 and 56.

[@GrammarHero]

@@drewhighfill9253 If you look at the last digit in 1344, it's 4, and since 4 is even, you know it's divisible by 2. If a number is divisible by 2, 3, 4, or 5, it is not prime! That question should take less than a few seconds to figure out! No math or long division needed!

[@bright8000]

Thank you so much for making this video. This video is indeed very helpful, sir. Thanks again, sir.

[@Tomxtech]

going to knock down these videos in two weeks and hopefully get a great passing score on my ASVAB the first try

[@GrammarHero]

Good luck!

[@sherikacarter9697]

Thank u for this!..🙌🙏

[@GrammarHero]

You are welcome. After watching this video, you should easily be able to tell if pretty much any number is prime, which should make those questions on the ASVAB very, very easy!

[@0nepercent16]

Great video 👍🏾

[@GrammarHero]

After watching this video, you should be able to quickly and confidently determine if almost any number is prime or not without having to do long division. Unfortunately, a lot of educators fail to make the connection between prime numbers and divisibility tests.

[@jericatf]

Another great video ❤️

[@GrammarHero]

Most of my videos are decent, I think.

[@jericatf]

@@GrammarHero you should never say that about your videos, you should always say to yourself that my videos help students succeed on the ASVAB, and help miraculously boost their scores ,you should feel proud about that you might not think your videos are the best, but they help students really succeed on the test and help boost their scores up that should be a feel good feeling to you ! And like I said before your videos help me improved on the math a lot like drastically I’ve been studying for four months now and me by just watching your videos I feel like I’m getting better every single day cause of you ❤️ thank you for what you are doing and thank you for your service! I can’t wait till I tell you the day I passed I took a Practice test on the recruiter site and got a 50% afqt my second highest score was in the mathematics knowledge thanks to you I hope this made you really feel good about what you are doing and looking at your videos differently god bless

Very helpful and useful

[@GrammarHero]

Thanks for the feedback, and good luck on your test!

[@javiervindel-zu1wi]

what are the chances of theses questions popping up in the asvab ?

[@GrammarHero]

You almost certainly will see a question about prime numbers.

[@dshanticalloway]

is 121 a prime number?

[@GrammarHero]

No. 121 / 11 = 11

[@bboytosoldier1588]

Can you make separate playlists identifying algebra and everything else not knowing where it all is overwhelming

[@GrammarHero]

Everything you need is in this playlist, and the playlist is already in order: kzbin.info/aero/PLhlU-GzAQeG1G47T95OqJkcjazmgLE6Tg Videos with yellow backgrounds = arithmetic reasoning Videos with red backgrounds = math knowledge. I won't be breaking it down any more than that, because a lot of the topics are interrelated. For example, you need systems of equations to solve some arithmetic reasoning problems, and you need some knowledge about triangles to solve arithmetic reasoning problems.
