What is the definition of an integer?
An integer is a whole number (not a fractional number) that can be positive, negative, or zero. Examples include -3, 0, 5, 100.
Explain the commutative property of addition.
The commutative property of addition states that the order in which two numbers are added does not change the sum. For any numbers a and b, a + b = b + a.
What is the difference between a prime number and a composite number?
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. A composite number is a natural number greater than 1 that has more than two distinct positive divisors.
Define the distributive property of multiplication over addition.
The distributive property states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. For any numbers a, b, and c, a * (b + c) = (a * b) + (a * c).
What is the absolute value of a number?
The absolute value of a number is its distance from zero on the number line, regardless of direction. It is always non-negative. The absolute value of x is denoted as |x|.
Explain the associative property of multiplication.
The associative property of multiplication states that the way in which factors are grouped in a multiplication does not change the product. For any numbers a, b, and c, (a * b) * c = a * (b * c).
