You seriously cannot be that thick....
ROMAN NUMERAL
16 = X(10)+V(5)+I(1)
HINDU-ARABIC NUMERALS
16 = 1(10)+6
It is LITERALLY the exact same.
Different numerals, same math [/quote]
You literally just calculated more factors with three then 1. and this is just a small case.
28 = 10(X), 10(X), 5(V), 1(I),1(I),1(I) or 228 = CCXVXVIII? It is visually and mentally quicker to just see "28" and know that it just means "28" or that 228 just means "228" if you know your arabic numbers you'll know what 28 and 228 means.
I agree, history we learn from the past helps pave the future but there is a difference between history and practice. We used history to look back at old era things like roman numerals and we developed better systems that do and should take priority over them. But taking time to teach something that will only be good in very limited, often histrorical situations is regressive
we can look back and acknoledge how people once did things but practicing how people once did things when there are better methods is only telling people to move backwards rather then forwards
You know they taught us more than one thing, right? Seven hours a day, five days a week, forty weeks out of the year, for twelve years. Roman numerals can be learned in an hour. We had time for other things.
Teachers would rather teach students how to use a calculator then an abacus because calculators are better.
They'd rather teach you how to read a clock then teach you how to read a sundial because clocks are better.
why is this not going to apply to teachers teaching roman numerals then arabic numbers when one is better.
and you can say "muh history" all you want but are you also advocating for teaching with abacuses and sundials too?
They actually taught us how to do the math in our heads so we didn't need either. Once again, point for "your schools suck."
You expect young children to learn, memorize and retain a number system within a single hour? You cant teach those same kids spelling OR math in just a single hour. If I was a teacher and said "Oh yea so this is roman numerals, thats a thing" and taught it for 1 hour I wouldn't expect 20 years later that those students would remember and be fighting people on the internet who didn't have your 1 hour lesson thing. I know that X means 10, V means 5 and I means 1 but I probably only learned it solely to read final fantasy covers as there is literally no other need for it in my life theoretically, I can read any number up to 100 just fine but I'd take me 3 seconds rather then the 1 second it'd take to see it in normal numbers
You do know we get basic schooling for twelve years, right? Or were you confused because I rendered the numbers in Latin letters rather than the Arabic numerals?
Funny you bring up the abacus. You don't think it is still used? Or a variation of it? Because it is sometimes still used today to teach younger children basic arithmetic concepts.
Or how about using blocks or other physical objects to simulate groups of numbers. Is that not a rudimentary form of an abacus?
Also fun fact about sundials as well. Have you ever seen an obelisk (very tall square tower with a pointed pyramid at the top) They are used in a lot of cities, those are actual sundials as well. Maybe not so much used as such, but they still exist.
Just because something may be obsolete to make way for better technology, does not mean that old technology is useless or gone forever
Digital clocks replaced analog clocks, why do we still use analog clocks in all buildings? But better technology for the future!
Oh right cause you do -all- math in your head and all people should. "burn all the calculators" says the mayor. They're only for stupid people who need handicaps.
Look mayor. There are some maths in this word that should not be reasonable expected to be done in your head. Even if you could, it wouldn't be efficient just like the abacus just like the sundial just like roman numerals. in all of these cases there is a easier, more common and efficient method schools would rather spend all the time teaching then waste any teaching you "fun fact" knowledge like old numerals or how to read a sundial
You're whining about a lot of things I never actually said. They taught us t do basic math in our heads, regular PEMDAS stuff. Incidentally, interpreting Roman numbers is such basic math that it can be read as easily as Arabic numbers once you've gotten it down.

Damn really? Second we learned numbers it was right to calculators and blocks and objects sure its good to learn to count real objects in the real world. I've never seen an obelisk in person and I'm sure any who do aren't using it as a sundial so its not a big surprise it wasn't taught
Your saying my school sucks because "They actually taught us how to do the math in our heads so we didn't need either. Once again, point for "your schools suck." what are you implying then? cause based on what I said it sounds like your saying calculators are only used for those who cant do head math which is a senseless parallel.
Not all remember, but we were all taught. So all it usually takes is a quick refresher for any Roman numerals that aren't used all that commonly. Just like with anything your taught and don't use regularly.
It takes me just as much time to read a Roman numeral as it does for me to read something in basic Spanish until around 50. Sometimes archaic things are used for the artistic nature. Roman numerals is one such thing. Makes things look fancy.
It's still taught in US schools because of that tendency. Super Bowl's were numbered with Roman numerals in the logo for years. It's on some analog clocks.
I'm stating--not even implying--that our schools taught us to do the math and not have a computer do it for us.
