4:12 “im gonna stop talking right now because i think we all need to focus“
Proceeds to make a random confession 🤣😭
Love the the little confessions inserted in each video I’ve watched over 100
Haha happy to hear this :) All the best and I think its awesome how many videos you have watched!
Sir i just wanted to say thank you for you educational video , i was so behind in matric 2021 i watched your videos in Maths and Physical sciences. Just Got accepted in UFS for Bsc Computer science. You really helped me alot i don't know how can i thank you you are such a blessing i always recommed you to my friends because the way you teach is impeccable. GOD BLESS YOU
Thank you so much for letting me know about this!! :) This is amazing and you had to put in the hard work :) Well done!!! :)
For those who are interested in the knuckle method and don't know it basically put both yoyr fists out. (Ignore your thumbs)
Now u have 4 knuckles of each hand, start from the left:
First knuckle- Jan = 31 days
the dip inbetween your knuckles(idk what its called😭) -feb = suppose to be 30 days but its feb so 28 days
3rd knuckle- March = 31 days
the dip- April = 30 days
4th knuckle- May = 31 days
Now the other fist,also count from the left (ignore thumb)
1st knuckle- June = 31 days
dip- July = 30 days
2nd knuckle- August = 31 days
dip- September = 30 days
3rd knuckle- October = 31 days
dip- November = 30 days
last knuckle- December = 31 days
To summarize it every knuckle represents 31 days and the dip in between your knuckles represent 30 days
Hope that helps🫡 (also you kevin😭)
June has 30 days and July has 31 *
Hey Kevin, if ure serious about your confession, I advise counting your knuckles and the spaces between them, every knuckle is 31 days, every 30 days is a gap between a knuckle, and u count knuckles on both hands
Appreciate you!! I also didn't know😭
Haha, I knew this since primary school 😂😂 it's really an amazing life hack🙂
I started watching your videos this year and my maths and physics marks improved drastically! Thank you Sir😊💯please do electromagnetism
Well done!!
Electromagnetism noted! :)
Kevins story time\confessions are goated
Thirty days has September, April, June and November. All the rest have 31 except for February alone. This month has 28 and 29 in each leap year. This is a little nursery rhyme I learnt to remember.
Great video ❤️❤️

Pls do more statistics videos like this it's so helpful !!!
hi kevin. just wanted to ask. when using the calculator for the mean, it gives the answer only. will i still get 2 marks or do i have to show my working out?
Back with the back in the day stories
Shouldnt you add all the numbers in the data set for the mean? I got 375/15 for 1.1.1 which is 75
The answer for the total is 25
same here kevin i dont know what months have 30 or 31🤣🤣🤣🤣🤣
I also don't know which months are which honestly 😭
I don't understand the last question.
isn't the answer to 1.1.1 3 because the number three is also outside one standard deviation of 25?
Just be careful. I nearly got caught out there as well. They only want it where it is one standard deviation GREATER than the mean. They only want us to look at the upper part.
@@kevinmathscience ohhh. I didn't realise that, thank you sir.
Hi Kevin thanks sm for the trig graphs, can you do more statistics for gr12 and 11 aswell and more difficult calculas notation examples ?
How did you get 375
Can you please make a playlist based on Electrodynamics And Optical Phenomena
Hello sir. Would you KINDLY make videos based on ELECTRODYNAMICS GRADE 12🙏🏾
I have noted this :)
My teacher makes us write the standard deviation method 😭 than use the calculator to calculate it,he said if we don't he will mark us wrong
How did you get the 20MB
80% of 25 is 20
Me too I only know that February has only 28 days 😅😂
Hey aren’t you supposed to arrange before putting before plucking the mean
He used the calculator method so the order doesn't really matter
Hie, on 1.1.3 how did you get the 80% average of 20mb
80×25/100
@laurikakritzinger2326 thank you ♥️
How did you get sir 375 for 1.1.3
Add all the numbers to get 375
Hey can you plz do measurements 🥺
Who's watching this video for maths June exam 2024😂😅
😹
Mind you im in matric 😭😭😭
😢
sir you are the best but i dont get 1,1,2 😪
😂😂😂I also don’t know which months have 30 days 😢
😂But using knuckles to count ain't that complicated
Compared to all this math you know haha
Haha I know but I always forget 😊
Give me a trig identitiy any day of the week and I will be fine. Ask me how many days there are in a specific month... Oh boy.. That's another story :)
grade 5
such a huge help , thank you @kevinmathscience 😇
I love the side story. 🫶🏼
