I learned lattice multiplication in school and it’s actually been my preferred method to multiply since third grade, so I recognized it on the bones immediately and felt extremely vindicated when you confirmed it for me later lol

Seeing these awakened long-buried memories in me of elementary school. I don't think we had these in particular, but we had similar things. I remember long, flat plastic rods with numbers along the side next to notches in the side that a small string would nest in as you wrapped and weaved it around the rod.

Abacus are Awesome as Well.

Seeing that you mentioned the abacus at the end, I think the Chinese/Japanese abacuses (?) are also worth talking about. Instead of using rows of 10 beads, they use columns of 5/7 beads separated by a bar in the middle, with the top beads representing a value of 5 and the bottom beads representing 1. A lot of children in Japan still learn to use the abacus, and both the Chinese and Japanese have used it to take mental calculations to the next level (6-digit multiplications in their head).

I used the lattice method all through school, I couldn't long multiply any other way and I still can't long divide. I always wondered if there was a whole school of thought in math that was like the lattice method. That drawn out grid helped me out so much as a person who is hands-on but I failed at math and nothing else was like the lattice method to me.

Same, lattice is how my primary school teacher taught. If I don't do the lattice method, I do another method where I split up one of the operands by tens place. So 1234*1234 becomes 1234*1000 + 1234*200 + 1234*30 + 1234*4

I would like teachers to teach this method when they see a child struggling with the usual way to calculate. But strange enough most teachers will give you less points on a right answer if the way you got this answer is not exactly the same way they teached! Isn't this totally wrong?

Love that "Ah-ha" (eureka) moment when you explained how to do the lattice method! Makes super sense and saves a TON of space. Can't wait to show my 13 year old who loves math as much as I do! Thankyou for sharing this!

I did not realize it at the time, but my 5th-grade teacher taught us lattice multiplication to demonstrate the fun of mathematics.

This is a prime example of how techniques/formulas have changed over time. Each generation seems to have been taught a different way to find the answer to math problems. A lot of them over complicate it, confusing people and making people, like me, _hate_ math.... This is really neat!

One of my first comp sci projects in college was making some of these out of cardboard and photographing me using them. What an odd professor, but he got the point across well.

John Napier: *invents extensive multiplication tools* Me, a distant relative: *traumatic war flashbacks of memorizing multiplication facts in 3rd grade*

The personality on display here is captivating. That Burroughs calculator bit was a 10/10

I watched a lot of your videos, amazing stuff. Napier was the man

I began a career i8n surveying in the early 1960's, several years before electronic calculators were available. Each field crew had at least one Curta mechanical calculator. If you can put your hands on one, I think many of your viewers would find it interesting.

True bro you are very good

The intro background music made medieval calculators sound as sick as a skateboarding ad.

if you put the smaller number on the right side you can also put decimals and get pretty accurate percentages. sometimes it can take some guessing to get the right decimal place in your answer.

Never seen or heard of this before. I thoroughly enjoyed this... Well done!

Your voice is very soothing. We learned about Napier Bones and abacus in history class in middle school. That's when they really taught history.🙂🙂

I remember at studying this school text book under computer subject. With just a picture and a paragraph, happy to see after so many years someone showed us this calculator.

I love how the bones are just the times tables for each number

I learned so many methods of calculation today thanks to you. Much obliged.

Wow, I spent a few years learning the Chinese abacus in my youth, got really quite fast at it, then never used it again and up until your demonstration, I had quite literally forgotten how it even worked. Kid me seemed like magic for most of my adult life.

them Bones

My uncle did business with Chinese people in the mid-'30s and he told us how they used abacus in a very expert and quick way. Never had a problem.

I've never seen this page, but I like it based off of this video. Especially The calculator part.

The most chill mathematician

The form of multiplication was used in the 1202 Liber Abaci and 800 AD Islamic mathematics and known under the name of lattice multiplication. "Crest of the Peacock", by G.G, Joseph, suggests that Napier learned the details of this method from "Treviso Arithmetic", written in 1478.

I didn't learn any of those methods! nice to see something new that I can still understand, except for the abacus.

I love seeing these sort of things

Hahahah first video I see from this KZreadr and pulls out the calculator joke 🤣 Subscribed and liked real quick.

I have often used the lattice method since I learned it in elementary school, but after elementary school and I got a bit older, I used it in my scratch paper that I had to turn in for proof that I did the work, and the teacher was like “what is this?” And I got points counted off for it. I tried telling them what it was and they said they’d never heard of it. Smartphones weren’t common at the time, so I couldn’t just Google it and show them. Then I started asking other people and they had no idea what I was talking about, even when I wrote it down and showed them. For years I started thinking I was just crazy and had made it up in my head or something, but I kept using it because it worked. Now I know I’m not crazy, those other people were just dumb or forgot about it.

This is the best video of this topic!!!

Ha ...... not just the 1600's, I learnt to use them at school in Edinburgh in the 1960's along with slide rules. Mind you, that was just down the road from Merchiston Castle, the family home of the Napiers.

Napier's Bones are a great teaching tool. I used them in the classroom many years ago.

This is a perfect youtube video. Perfection.

Lol new to your channel. Loved how gitty you were over that calculator

this was so much fun to watch. thank you.

This was really COOL! i used to have an old mechanical pocket calculator, I loved it.

I didn't recognize the formula until he draw the box, I was stunned I was using it the whole time.

When I was in high school in the 1960s they still taught how to use a sliderule for the advanced students. In my first job in the 1970s I used the old manual calculator that had rows of numbers to punch.

I enjoyed this video waayyy more than I thought I would. Subscribed.

I subbed bcuz I love, used and understand the Napier Bones. We made small ones from popsicle sticks, just for fun in middle school. I loved the clicks of the Abacus.🙂🙂🙂

So cool to see a demonstration of these! Btw, the sound level for the VO was a little low and the music a little high. Overall, another great video. Keep it up!

I shall now and forevermore use the diagonal lattice system. It's so much easier 😲

That music at the start got me thinking "why does this sound familiar?" And i saw a minecraft lego ad in my recommended and it was this same music it used.

This is totally awesome. I'm not very good at math but I feel like if I was taught this as a kid I probably wouldn't be as bad at math! Hell maybe it might have boosted my confidence in mathematics. Definitely a good eye opener of a video!

Sometimes I want to pick all ytubers and time travel them back to when I was a kid, this makes sooo much more sense

How happy you were with your big calculator made me happy.

I haven’t subbed this hard in years

When I was younger I could never figure out multiplication and only knew lattice, so it's interesting to see that other people used I'd more frequently for more applications

subbed this stuff blew my mind

You could also use jetons on an exchequer table, or even calculi on a sand table or Salamis-styled board.

I learned the abacus as a child, this thing is faster in operation speed but it needs time to setup. Plus, it can be arbitrary length - abacus is kinda limited and really unwieldy. Good abacus operator can calculate really fast and with enough practice, it's muscle memory. I wonder how fast can the calculation be if people practice using this enough.

My brain died in the abacus demonstration

I think a teacher would be impressed if you used this in highschool

In my school system we actually learn multiplication using the lattice method! We get taught the older method and the lattice so we could use what works best for us

Thanks man just found another way to multiply big numbers

I remember that my 3rd grade teacher taught my class how to make these: I completely forgot how, until now.

How does this channel not have more subs wtf

holy crap, that's magical.

that's a pretty cool way to calculate things

This video is as though ripped from the internet of my childhood and brought here to the internet of my sad late 20's.

this video was awesome as someone who like numbers its cool to see a old way of computation that works the way my brain dose math

A well formulated video

YT Algorithm: Wanna see a Stick Calculator from 1600s?? Me, watching in a sunday: WHY NOT?!

You could do multi digit with multi digit using the bones by writing out the rows on a different paper and doing lattice on them. Pretty sick. Also first time I ever saw someone explain the abacus

Ok, you had me at the calculator. Liked, commented, and subscribed!
