Exploring Integer Operations and Absolute Value

The video reviews key concepts about integers, including their definition, ordering, and operations like addition, subtraction, multiplication, and division. It also covers absolute value, explaining it as the distance from zero on a number line. The tutorial provides examples to illustrate positive and negative integers and their operations, ensuring a comprehensive understanding of these mathematical concepts.

What is an integer?

• Any number on a number line, including fractions.

• Only positive whole numbers.

• Whole numbers that can be positive, negative, or zero.

• Only numbers above zero.

What does absolute value represent?

• The positive distance from zero.

• The total distance traveled.

• The negative distance from zero.

• The numerical value regardless of its sign.

What is the absolute value of -7?

• -7

• -0

• 0

• 7

What does a negative outside the absolute value signs indicate?

• The result turns negative.

• The result is always positive.

• The absolute value is ignored.

• The value inside becomes negative.

How do you add a positive and a negative integer?

• Add the two numbers and keep the sign of the larger.

• Always results in a negative number.

• Multiply the two numbers.

• Subtract the smaller number from the larger and take the sign of the larger.

If you subtract a larger positive integer from a smaller positive integer, the result is:

• Depends on the numbers

• Zero

• Always negative

• Always positive

What is the result of adding two positive integers?

• Zero

• A negative number

• Cannot be determined

What is the result of multiplying two negative integers?

• Zero

• A positive number

• A negative number

• Cannot be determined

What is the result of dividing a positive number by a negative number?

• A negative number

• Cannot be determined

• Zero

• A positive number

Which of the following is true about the multiplication of integers?

• A negative times a positive is positive.

• A negative times a negative is negative.

• A positive times a positive is negative.

• A negative times a negative is positive.
