Thanks a lot, Jay!
My pleasure! 🙂
very helpfull thanks
You're welcome!
Super, dooper trick,. Take a bow ❤
😀 Thanks
What is the length took by compass
Any length you like
Ty so much 😭 this helped alot
You're welcome!
3:50 So this cannot to be factories , QUADRATIC FORMULAE only
Be patient! Keep watching the video for another minute and you will see how to factorise...
How did you get 2×7/5 -3 = -1/5
At what time in the video?
@@MathsWithJay no no i got the answer no need to explain
Thank u for help us
No problem
Thanks
No problem
Thank you so much so simple and easy 🎉
You’re welcome 😊
thanks
You're welcome!
Thank you man
You're welcome!
when u do the factorising bit (5y-2)(y-6)=0 what did u do with -32y did u just leave it or
5y x -6 = -30y and -2 x y = -2y, adding -30y and -2y gives -32y
very good video but I had to replay the video many times because there weren't any subtitles, and it's quite hard to catch up with your British accent, can you please add subtitles ? 🙏
Thank you for your feedback. Most of our recent videos have subtitles. Does it help to slow down the speed of the video?
@@MathsWithJay a bit but thankyou for responding
It did not help for me too sorry😢
Does this help: ua-cam.com/video/soCVhO3eN4E/v-deo.html ?
you are not explaning how to do it you are just doing the working😢

This is very insightful, you have really help me, which app do u use in making this video
You're welcome. I used Camtasia software to record and edit the video.
@@MathsWithJay It's amazing... Please keep it, you're doing a great job
Thank you so much
You're most welcome
Mr jay i don't understand lattice method yes i understand but when i use a cluebord i can't get. The answer but i will always. Watch your videos i will understand. Step by step
What is a cluebord?
I greatly thank you for helping me
You are most welcome
hii can u tell me how we got 78 from 918
At what time in the video?
What is meaning of nth term
n is a whole number, so when n is 1, it is the 1st term, when n is 25, it is the 25th term...
@@MathsWithJay thank you mam
I have exam in three hours about this topic , let's goooo!!!
Hope it went well!
@@MathsWithJay it went very well , we had question about this topic , and I did it easily thanks to your video!expecting my grade to be between 75 - 100 thanks again👍🏻🙌
So if we have sin and cos with odd power in same question we choose the lower power right? what if the powers are equal we choose whatever we want?
Yes...you could try it out to see which one you prefer
Thank you i just understand now
You're welcome!
I don’t understand the last part where you bracket and try to get -32y
At what time in the video?
@@MathsWithJay towards the end
Where's 2 Coming from
At what time in the video?
Interesting
Thanks
Man U saved me I had exam tomorrow
I hope it went well
Amazing simple to the point explanation
Glad you think so!
Isnt y=-0.4 and -6
Remember that you can check your solutions by substituting them in to both equations
Hi ma'am how do you reverse you calculator from that to normal 😢cause mine won't go back please help I'm writing my paper on Monday
ua-cam.com/video/fgUgnG6UEo0/v-deo.html shows how to reset
Can anyone explain the last step. How did you get 78
At what time in the video?
u saved me ..... THANKK YOUUU
Welcome!
My mom said I have to learn things incase I don't have a calculator. I think it's more common for people to have their phone on them which is a calculator than to have a pencil and paper on them as well as a flat surface to write all of this on and the time it takes to do it. Honestly in the real world, Lattice Multiplication is outdated. I call it the "Dinosaur" or multiplication.
It's also known as Napier's bones
Me being here one day before the examination is.........wow😅😅
Wow! Hope it went well
mine's today i only have 2 hours to review before the test 😅
Tanks pup
How do find it if you’re multiplying or dividing?
ua-cam.com/video/ggO5aKoopDw/v-deo.html is a doubling example
I had a test the next day and this REALLY helped. Thank youuuu
Welcome!
I'll be using this method moving forward in life... I used to just say what's 4308 × 100? 430800 and then i multiply standardly 4308 × 9 and get some answer A now i have: 430800 - A = 4308 × 91
It's good to have another method to use as a check
So what is the benefit of the lattice method over the other method?
Students who are dyslexic often find this method simpler
Does this work for negative numbers?
Yes
heard someone talking about "lattice multiplication" on youtube shorts and literally had never heard of it thats such a weird way!
Some people prefer this method
We never used this again after 4th grade lol
Everyone has to start somewhere
Take care 😊😊😊😊😊😊
Thank you
You help me with my homework. Thank you so much ❤❤❤😊😊😊
