15 Points Per Correct Answer - No time limit  



1. If a and b are positive integers, then there exists a positive integer d which satisfies the following properties:

1. a is divisible by d and b is divisible by d
2. Suppose D is another positive integer having the property a is divisible by D and b is divisible by D. Then d is divisible by D.

What is d known as?
    The least common multiple of a and b
    The quotient of a and b
    The product of a and b
    The greatest common divisor of a and b


2. If a and b are positive integers, then there exists a positive integer m which satisfies the following properties:

1. m is divisible by a and m is divisible by b
2. Suppose M is another positive integer having the property M is divisible by a and M is divisible by b. Then M is divisible by m.

What is m known as?
    The quotient of a and b
    The greatest common divisor of a and b
    The least common multiple of a and b
    The product of a and b


3. Let Q be the set of all numbers of the form a/b where a and b are both integers and b cannot be 0. What is the set Q called?
    The set of rational numbers
    The set of complex numbers
    The set of real numbers
    The set of natural numbers


4. Let a and b be positive integers. Then there exist integers q and r which satisfy

a = b*q + r

with r greater than or equal to 0 and less than b. What is r called?
    The quotient
    The remainder
    The dividend
    The divisor


5. Suppose a and b are real numbers (b positive) which satisfy a^2 = b. What is a called?
    The square of b
    The exponent of b
    The base 2 logarithm of b
    A square root of b


6. Let a be a real number. Then there exists a real number b which satisfies:

a + b = 0.

Furthermore, if c is another real number which satisfies a + c = 0, then c = b.

What is this number b called?
    The reciprocal of a
    The additive inverse of a
    The square of a
    The square root of a


7. This is a type of sequence of numbers in which the difference between successive terms is constant.
    Harmonic series
    Geometric progression
    Arithmetic progression
    Geometric series


8. Which function f has the following definition for a real number x?

If x is greater than or equal to 0, then f(x) = x, otherwise f(x) = -x.
    f(x) = -x
    f(x) = the square root of x
    f(x) = x^2
    f(x) = the absolute value of x


9. A positive integer can be written uniquely (up to order of the factors) as a product of powers of distinct primes. What is this theorem called?
    The Fundamental Theorem of Algebra
    The Fundamental Theorem of Galois Theory
    The Fundamental Theorem of Calculus
