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 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 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?

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
