Adding Integers with Different Signs

In this video, Mr. J explains how to add integers using different strategies. He covers four examples, demonstrating how to handle both different and same signs. The video includes methods like using absolute values and mental math to find solutions. Mr. J also mentions a related video on using a number line for visualization.

What is the first step in adding integers with different signs?

• Add the integers directly.

• Divide the integers.

• Find the absolute values of the integers.

• Multiply the integers.

When adding -5 and 7, what is the absolute value of -5?

• -7

• 7

• 5

• -5

Using mental math, what is the result of -5 plus 7?

• 0

• -2

• 2

• 12

What is the result of 20 plus -12 using absolute values?

• 32

• 8

• 12

• -8

Using mental math, what is the result of 20 plus -12?

• 12

• 32

• 8

• -8

What is the sum of -13 and -4 using absolute values?

• 9

• -9

• 17

• -17

Using mental math, what is the result of -13 plus -4?

• 9

• 17

• -9

• -17

What is the sum of -25 and -8 using absolute values?

• 17

• -17

• -33

• 33

Using mental math, what is the result of -25 plus -8?

• 17

• -17

• 33

• -33

What is the key concept when adding integers with the same signs?

• Add the absolute values and use the common sign.

• Divide the integers.

• Subtract the integers.

• Multiply the integers.
