Understanding Integer Multiplication with Examples

Slide Note

Explore the concept of multiplying integers with examples of same and different signs. Learn how the product changes based on the signs of the numbers involved. Step-by-step examples demonstrate how to determine whether the result will be positive or negative. Additionally, engage in practical scenarios, such as measuring the depth of a submersible, to apply integer multiplication in real-life contexts.

Please get out your homework and a red pen and set it to the side. Next, make sure your journals are labeled: Solve: 1. -2 + -7 3-4 : Multipy Integers. 2. -4 + 8 Finally, complete the quick check to the left in your journal on the page you just labeled. 3. -7 + 4 4. -8 (-2) 5. 8 - 12 Thanks!

ANSWERS 1. -9 2. 4 3. -3 4. -6 5. -4 Course 2, Lesson 3-4

The Number System WHAT happens when you add, subtract, multiply, and divide integers? Course 2, Lesson 3-4

The Number System To multiply integers with same and different signs Course 2, Lesson 3-4

The Number System Multiply Integers with Different Signs Words different signs is negative. The product of two integers with Examples 6( 4) = 24 5(7) = 35 Course 2, Lesson 3-4

Step-by-Step Example 3( 5) 5(-4) -6 * 8 3 * -9 Need Another Example?

The Number System Multiply Integers with the Same Sign Words The product of two integers with the same sign is positive. Examples 2(6) = 12 10( 6) = 60 Course 2, Lesson 3-4

Step-by-Step Example 11( 9) -6 * -8 (-4)2 (-8)2 Need Another Example?

Step-by-Step Example 3( 4)( 2) Determine if the answer will be positive or negative first Need Another Example?

Need Another Example? You try: ( 2)( 5)( 6). 60 Answer

Step-by-Step Example Let s talk about this one A submersible is diving from the surface of the water at a rate of 90 feet per minute. What is the depth of the submersible after 7 minutes? Need Another Example?

Need Another Example? A mine elevator descends at a rate of 200 feet per minute. Write a multiplication expression to represent the total distance descended after four minutes. Then find the product and explain its meaning. 4( 200); 800; In four minutes, the elevator will descend 800 feet. Answer
