Multiply integers

Learning Objectives Identify positive and negative integers. Recall basic multiplication facts for whole numbers. Apply the rules for multiplying a positive integer by a negative integer. Apply the rules for multiplying a negative integer by a negative integer. Calculate the product of two or more integers. Solve simple real-world problems involving the multiplication of integers. Have you ever thought about what happens when you multiply numbers that are 'below zero'? 🥶 Let's find out how to multiply positive and negative numbers! In this lesson, you'll learn the simple rules for multiplying integers, including positive and negative numbers. Understanding these rules will help you solve many different types of math problems and understand situations in...

TermDefinitionExample IntegerWhole numbers and their opposites (negative numbers), including zero. Integers do not include fractions or decimals.Examples of integers are -5, -2, 0, 3, 10. Positive IntegerAn integer that is greater than zero. These numbers are usually written without a plus sign, but a '+' can be used.1, 7, 25 are positive integers. We can write them as +1, +7, +25. Negative IntegerAn integer that is less than zero. These numbers are always written with a minus sign in front of them.-1, -7, -25 are negative integers. ProductThe result you get when you multiply two or more numbers together.In the equation $3 imes 4 = 12$, the number 12 is the product. Absolute ValueThe distance of a number from zero on a number line, always a positive value. It tells you the &#03...

Multiplying Two Positive Integers $ (+) \times (+) = (+) $ When you multiply two positive integers, the product is always positive. This is just like the multiplication you already know. Multiplying Two Negative Integers $ (-) \times (-) = (+) $ When you multiply two negative integers, the product is always positive. Think of 'a negative of a negative' as becoming positive. Multiplying a Positive and a Negative Integer $ (+) \times (-) = (-) $ and $ (-) \times (+) = (-) $ When you multiply a positive integer by a negative integer (or a negative by a positive), the product is always negative. If the signs are different, the answer is negative. Multiplying by Zero $ \text{Any Integer} \times 0 = 0 $ Any integer, whether positive or negative, multiplie...
