- What is an integer? An integer is a whole number, either positive, negative, or zero.
- How do you represent integers on the number line? Integers are represented on the number line by evenly spaced points to the right of zero for positive integers and to the left of zero for negative integers.
- What are the properties of integers? The properties of integers include closure under addition, subtraction, and multiplication, associativity, commutativity, distributivity, and the existence of additive and multiplicative inverses.
- How do you add and subtract integers? When adding integers, if the signs are the same, add the absolute values and keep the sign. If the signs are different, subtract the absolute values and take the sign of the integer with the largest absolute value. To subtract integers, add the opposite.
- How do you multiply and divide integers? When multiplying integers, if the signs are the same, the product is positive. If the signs are different, the product is negative. When dividing integers, if the signs are the same, the quotient is positive. If the signs are different, the quotient is negative.
- What is the greatest common divisor (GCD) of two integers? The greatest common divisor (GCD) of two integers is the largest positive integer that divides both integers exactly.
- What is the least common multiple (LCM) of two integers? The least common multiple (LCM) of two integers is the smallest positive integer that is a multiple of both integers.
- How do you find the absolute value of an integer? The absolute value of an integer is the distance of the integer from zero on the number line. The absolute value of an integer is always positive.
