This is embarrassing but it is what it is. I'm a 37 year old man, never understood or was never explained what prime numbers are. Thanks to you Sir, I now know. Thank you 🙏🏽

[@sylviawild9015]

Sometimes because my age I feel the same, but I try not to forget that never is late to learn

[@Orzesss]

your age is prime

[@alansun70]

Numbers only divisible by 1 & itself. I can memorize all the 2 & 3 digit primes. 4 digit ones are tough. I can mentally break down 3 digit numbers.

[@bnm-g4k]

dont be embarrassed you are never too old. I never understood this topic back in school and im here too. you keep pushing

[@chill_orange8374]

[@emmc1105]

Thank you!! I'm in college math remedial and i didn't understand in class until this video. It's been more than a decade since I've touched this kind of math

[@tiffany5333]

You are a life savor. I am 20 years old and barely learning the basics of math but you made it so easy.

[@samarahandrew9105]

[@huseyinkagantoy5469]

Adding 1 to a random number changes all the factors of that number. 48= 2*2*2*2*3 Like 49=7*7. In the light of this information, we know that if we start from 1 and multiply the numbers consecutively and add 1, the resulting number is not divided by any of the previous multipliers. that is, if we add 1 consecutively to infinity, we can get a prime number at infinity. in an other saying forever! +1 is definitely a prime number. #math #maths #mathematics #primenumbers
