Are there any countries that don't use base 10 mathematics?

None that I know of currently.  In all but the most isolated, primitive societies, the base 10 is used.  (Of course computers use base 2, but they hardly qualify as a civilization.)\n\nThere is prehistoric evidence that a few tribes used a base 5 system; the Romans had a complex system that was very loosely based on 10, and the ancient Mayan civilization used base 60!

Americans say "Math" while Britons say "Maths"

not necessary to have whole numbers...you can have decimals like 2.79 5.5 3.2 like these..all these depends on the key you used to represent the data

Well the basic principles of mathematics are available to everyone.  People from any background intuitively understand core mathematical principles, such as A is equal to A, This amount plus this amount creates a new amount.  7 is greater than 5.\n\nLanguage on the other hand is entirely learned, and cannot be assumed without some experience in a culture.  Also language involves several different parts of the brain to speak, read, comprehend, and develop ideas.  \n\nOn the other hand, some mathematical constructs like calculus can only be shared through the use of a language, like english.  At this point mathematics can be much more elusive to understand than english.

I'll just mention Indian schools since I live in India and tutor American students\n\nIndian schools do not have calculators in class till about the age of 15 and that too only for very specific courses\n\nAmerican schools, i believe allow calculators a lot earlier?

Not in the United States

The Czech Republic does. You have to pass a lot of difficult tests to be accepted and to stay in University though. Otherwise, you have to pay for expensive, lower quality private university.

That is a totally false claim. The link below will take you to a table showing IQ by nation. The US is not bottom.

No, the children in the U.S. are not as educated as in other countries. In many European countries, every student who graduates from secondary school has studied advanced math, chemistry, physics, biology, and can speak, read, write, and understand at least two foreign languages. In the U.S. students can graduate having taken Algebra 1 and Geometry, two years of science, and a year or two of a foreign language - taught from the perspective of "we will never need this, except to graduate from school, so it doesnt matter if we can even say 'where is the toilet' in the language we are studying". It is appaling that the U.S. has such low education standards when they insist they are the most civilized and advanced nation.

Try the bitesize website. Which is a UK school revision site. But math is the same the world over so that should not matter

well i think school systems vary in different states. i always hear about the NY school system where i live, and i think its on the right track right now. also, its a little known fact that the United States has one of the lowest standards of learning in the world. out of the top educated countries(i think about 12) were 10th!!! how embarassing.

im sure there are plenty of countries using it.... possibly the british army ..... most military branches dont give out information on what types of training exercises they have that could possibly get into the wrong hands

not true.  visit this site for the mississippi content standards for teaching math: http://www.mde.k12.ms.us/acad/id/curriculum/math/mathk_6.pdf

If I understand your question then yes, that's the beauty of fractions.  As helpful as decimals are, they are base-10 meaning that you have 10, 100, 1000, 10000, etc.  But a fraction can use thirds, sevenths, 29ths ....  They are harder to work with but they can represent more numbers because they aren't base ten (think of it like this, 1/3 is an easy fraction, but as a decimal it .333333333333333333 (and goes on forever).

England for a start. We use feet, inches, pounds, miles and stone, we're rather resistant to the metric system. America uses some of it I believe with things liek miles and lbs but i think slowly they're turning to metric more and more. The rest of Europe is very strictly metric, leading the way is France

There are none.\n\nMetric units all use base ten. We have ten fingers, so the whole decimal system is based on base ten.\nThis in turn allows for easy conversions and calculations between smaller and larger scales as they are all done in multiples of 1000 when using engineering units.\n\nSome imperial units have a finer scale than the metric equivalent, which simply means that an integer in the imperial equates to a decimal place on the metric scale. But not using a decimal place does not make it any more accurate.

Theres no such thing, because each US state (& then there's the US national standards) & each country have their own educational standards. You can't compare worldwide because of economic and cultural differences. Usually there are some very good schools in metro areas, but there's always the downfall of them being huge and overcrowded even though they have an abundance of resources. Suburbs and rural areas are sometimes the place to look. The circumstances vary so much from person to person and school to school, that that's why so many schools exist --- to harbor everyone's needs.
