what are the seven properties of rational numbers
Subtraction and addition are not properties of numbers themselves: they are operators that can be defined on sets of numbers.
it was often attributed to Pierre de Fermat but is actually found by Arabian al-Banna in the late 13th or 14th century
No, they are not the same. Axioms cannot be proved, most properties can.
Numbers divisible by 1 & number itself are called prime numbers. These numbers also have the property to be odd numbers.
220 & 284
Amicable pairs are two numbers that are related in such a way that total of the divisors of each is the same as the other number. This is the case of numbers 220 and 284.
The amicable numbers 2620 and 2924 were discovered by the ancient Greek mathematician Pythagoras. These numbers have a special relationship where the sum of the factors of one number equals the other, and vice versa.
An amicable number is one of a pair of numbers which have the property that the sum of the divisors of each, excluding itself, is equal to the other number.
Pythagoras discovered the smallest pair of amicable numbers: 220 and 284. The Arab mathematician Al-Banna found a larger amicable pair, 17,296 and 18,416, but European mathematicians were not aware of this discovery. Pierre de Fermat rediscovered this amicable pair in 1636. Rene Descartes rediscovered another amicable pair known to Arab mathematicians in 1638 - the pair 9,363,584 and 9,437,056. Leonhard Euler found 30 pairs of amicable numbers by 1747 because he developed a formula that could produce amicable pairs. B. Nicolo I. Paganini found the smaller amicable pair 1184 and 1210 that had been missed by other European mathematicians in 1866.
Amicable numbers are two different numbers so related that the sum of the proper divisors of each is equal to the other number. For example, the smallest pair of amicable numbers is (220, 284)
Amicable is stressed on the first syllable.
Amicable numbers are pairs of numbers for which the sum of the proper divisors (the divisors except for the number itself) equals the other number in the pair. The smallest amicable pair is 220 and 284. The proper divisors of 220 are and the factors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, and 110, the sum of which is 284. The proper divisors of 284 are 1, 2, 4, 71, and 142, the sum of which is 220.

There are no exact rhymes for the word amicable.
The prefix for "amicable" is "a-", which means "not" or "without."
