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.

@@GrammarHero It is not a prime number. It can be divisible by 2. 2 and 672 = 1344
@drewhighfill9253
@drewhighfill9253 3 года назад
@@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
@GrammarHero 3 года назад
@@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!

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!

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.

@@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

Can you make separate playlists identifying algebra and everything else not knowing where it all is overwhelming
@GrammarHero
@GrammarHero 3 года назад
Everything you need is in this playlist, and the playlist is already in order: ru-vid.com/group/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.
