Description : The relation "divides" on a set of positive integers is .................. (A) Symmetric and transitive (B) Anti symmetric and transitive (C) Symmetric only (D) Transitive only

Last Answer : (B) Anti symmetric and transitive Explanation: The ‘divide’ operation is antisymmetric because if a divides b does not necessarily implies that b divides a. If a divides b and b divides c then a divides c. So, it is transitive as well.

Description : When the celebrated German mathematician Karl Friedrich Gauss (1777-1855) was nine he was asked to add all the integers from 1 through 100. He quickly added 1 to 100, 2 to 99, and so on for 50 pairs ... 1,000,000,000.That's all the digits in all the numbers, not all the numbers themselves. -Riddles

Last Answer : The numbers can be grouped by pairs: 999,999,999 and 0; 999,999,998 and 1' 999,999,997 and 2; and so on.... There are half a billion pairs, and the sum of the digits in each pair is 81. The digits in the unpaired number, 1,000,000,000, add to 1. Then: (500,000,000 X 81) + 1= 40,500,000,001.

Description : If A B and C are counting numbers and both A and B are multiples of C what can you say about A plus B?

Last Answer : A + B is also a multiple of C.-------------------------------------------let k, m and n be integers. Then:A = nC as A is a multiple of CB = mC as B is a multiple of C→ A + B = nC + mC = (n + m)C = kC where k = n + mkC is a multiple of C.Thus A + B is a multiple of C.

Description : When A B and C are counting numbers and both A and B are multiples of C what can you say about A plus B?

Last Answer : If A and B are multiples of C, then A + B is also a multiple ofC:If A is a multiple of C then A = mC for some integer mIf B is a multiple of C, then B = nC for some integer n→ A + B = mC + nC= (m + n)C= kC where k = m + n and is an integer→ A + B is a multiple of C

Description : If A over B is a fraction in simplest form with A and B counting numbers and a terminating decimal form why must B be a factor of a power of 10?

Last Answer : Suppose A/B equals a decimal fraction F, which has d digits after the decimal place and then terminates.Then (A/B)*10D = F*10D is an integer.That is A*10D/B is an integer.A and B are coprime so they have no factor in common and therefore B must divide 10D.

Description : When A B and C are counting numbers and both A and B are multiples of C what can you say about A plus B?
