Why are prime numbers called prime?
The term originated from the Latin word primus, meaning first in importance. Prime are the important main ingredient of numbers, for every number greater than one is either a prime or a product of primes.
How is adding rational numbers different than adding whole numbers?
Whole numbers are rational numbers with a denominator of 1. The difference with general rational numbers is that the denominators are likely to be different and they must be made the same by converting the fractions into equivalent fractions with the same denominator before the addition can be done - by adding the numerators and keeping the denominator, and simplifying (if possible) the result. With whole numbers the denominators are already the same (as 1) and so the addition can be done straight away.
What are the disadvantages of the Hindu-Arabic number system?
The main disadvantages of the Hindu-Arabic number system is its inability to give an exact value to irrational numbers such as: pi, surds, recurring decimals and even infinity itself.
What is the 2 main subsets of real numbers?
The two main DISJOINT subsets of the Real numbers are the rational numbers and the irrational numbers.
What is a complex fraction?
That means that there is a main fraction; the numerator, the denominator, or both, of it, are in turn fractions.
How do subtract fractions?
all you have to do is follow the same algorithm for adding a pair of fractions together. the main step is to find common denominators between the two. to do this, you need to find the least common multiple. another way you could find a common denominator is just by changing them into decimals, and adding them normally like whole numbers with the decimals lined up correctly.
What are the disadvantages of the decimal system based in fractions versus decimals?
The decimal system is based on 10 and the powers of 10. The main disadvantage is that 10 is divisible by only 2 and 5. So commonly needed fractions, such as a third end up being infinite decimals.
What are the main prime numbers in 22?
2 and 11 are the prime numbers that when multiplied together equal 22.
When multiplying decimals with whole numbers do you line up the whole numbers?
Hey awesome Question. The answer is no you do not have to line up the decimals when multyping only when adding and subtracting. The main thing is when you multiply make sure you put the decimal in the right place in your answer. YOu count how may places their are behind the decimals in BOTH numbers then you make sure their are that many places behind the decimal in you answer. :)

How do you compare two fractions?
Three main ways:Convert them to equivalent fractions with the same denominator. Then smaller numerator = smaller fraction.Convert them to equivalent fractions with the same numerator. Then smaller denominator = larger fraction (this is useful for comparing reciprocals of integers, since the numerators are already all 1).Convert to decimals. This is essentially converting to a common denominator (bullet 1) that may be a large power of ten.
How do you get a decimal from a fraction?
Well the bottom number on the fraction means the total amount of that number until that number equals 1. like 4/8 is only half of 8s total. but 8/8 is a total of 1. and 16/8 is a total of 2 8s. If we take the number 1 or 2 we need to recognize that that really means 1.00000 infinitely repeating and 2.00000 infinitely repeating. If we take 4/8 and recognize that that means a half... and you know that a half equals 0.5 in decimals then that is a basic explanation of a decimal from a fraction. The main idea of a decimal is to indicated the numbers between numbers. Like there is an infinite amount of numbers between 1 and 2 and the same with 2 and 3 and the same with 3 and 4 and it goes on forever between every single number. numbers between numbers are called decimals and fractions. decimals and fractions are the same but just written in a different form. decimals are rounded off and fractions are exactly perfect. I can't really explain how to get a decimal from a fraction. There is no exact one way since there are an infinitely of decimals and fractions and an infinite of combinations of them both. You just need to practice and recognize patterns. patterns like 3/5 is equal to 0.60 as a decimal. or 6/8 is also 3/4 as a fraciton and is written as 0.75 as a decimal. just realize that the bottom number (called the denominator) on the fraction is the total amount that the topp number has to get to for that fraction to equal 1. 5/5 = 1 2345636/2345636 = 1 (5/6)/(5/6) = 1 3.4/3.4 = 1

What are the similarities between prime and composite numbers?
Both belong to set of whole numbers. There are infinite prime and composite numbers.
What are the main differences in a distallation columns fractions?
The main differences in distillation columns fractions are the separation of a mixture. It is component parts or factions that separate chemical compounds.
What is the difference between adding whole numbers and adding decimals?
The main difference is that with whole numbers the decimal point is "hiding" (after the last digit of each whole number) whereas with decimal numbers it is clearly visible. In both cases the numbers are added with the decimal points aligned - with whole numbers there are no digits after the decimal points so the decimal points are not written, but if they were they would be visible after the last digit of the whole numbers and they would be automatically aligned; with decimal numbers there may be a different number of digits after each decimal point so it is up to the person doing the arithmetic to ensure the decimal points are aligned.
How many numbers are in roman numeral?
3999 whole numbers and 12 duodecimal (base-12) fractions.
