No it isn't.
No, American and British tablespoons are the same volume measurement, approximately equal to 14.8 milliliters. However, British cooking recipes often use the metric system, where a tablespoon is equivalent to 15 milliliters.
If you mean a number system analogous (similar) to our decimal system, the base for such a number system can be any integer, 2 or greater. In other words, the base can be 2, 3, 4, 5, etc. You need as many different digits as the size of the base (decimal is in base 10, so you need 10 different digits).
The number of different symbols is the same as the base. So the answer is 2 and the symbols are 0 and 1.
In practice, the British mercantile system worked so that the Colonists were being regulated by British rules. The Colonists resented this and the passing of the Stamp Act was said to be the last straw that pushed them over the edge as far as hostility toward the British.
The British wanted a system of judiciary so that they can suppress the Indians who raised their voice against them by using laws and courts
Number systems are usually based on something. Our number system is based on 10; this is because we have 10 fingers. If we had 8 fingers then our system would be based on 8. Then we would have a completely different system. In this system, 11 would come after 8 because 8 is the highest number in the system, so after you reach 8 you start over but you increase the number in front by 1.
The number system they used back them is the sexagesimal system. Our system has 10 digits from 0 to 9. So they used a system with 60 digits. That's why it is called a sexagesimal system. So make that a 60 for the Babylonian number.
Metric system so grams, kilograms, etc
There are many types of number systems. The common one is base-10. Base-2 is used in computer language and so is the hexadecimal system which is a Base-16 system.
The British parliamentary system was certainly an influence on the design of the US constitution, but remember that the US was created specifically as a revolution against the British system as well, so it would not be correct to say that the US is based on the British Parliament.
The radix is a property of a numerical system, not an individual number. It is the number of different digits (or characters) used by the system to represent all numbers. Thus the radix of the binary system is 2: 0 and 1 the radix of the octal system is 8: 0,1,2,3,4,5,6 and 7 the radix of the decimal system is 10: 0,1,2,3,4,5,6,7,8 and 9 and so on. Since a number cannot have a radix, the question does not make sense.
Since the middle 1960s - for around 50 years now - the British billion has been the same as the US billion, so I am not sure what the question means by "british system".
