Adding Integers with Different Signs

This lesson covers the addition of integers, focusing on both same-sign and different-sign scenarios. Students learn to add integers by keeping the sign the same for same-sign numbers and using absolute values for different-sign numbers. The lesson includes various examples and methods, such as using number lines and counters, to reinforce understanding.

What is the result of adding two positive integers?

• A negative integer

• A positive integer

• Zero

• An integer with no sign

When adding two negative integers, what should you do with the sign?

• Ignore the sign

• Keep it negative

• Change it to positive

• Make it zero

How do you determine the result when adding integers with different signs?

• Add the numbers and keep the sign of the smaller number

• Always result in a negative number

• Subtract the smaller absolute value from the larger and keep the sign of the larger

• Always result in a positive number

What is the absolute value of -7?

• -1

• -7

• 0

• 7

Which method can be used to visualize adding integers with the same sign?

• Using a protractor

• Drawing counters

• Using a calculator

• Using a ruler

If you have -6 and add -3, what is the result?

• -3

• 9

• 3

• -9

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

• Ignore the signs

• Add the numbers directly

• Multiply the numbers

• Find the absolute values

When adding 5 and -3, what is the result?

• -2

• 2

• 8

• 0

What is the result of 42 plus -56?

• -98

• 14

• -14

• 98

In the final example, what is the importance of keeping the sign of the larger absolute value?

• It is not important

• It determines the final sign of the result

• It helps in multiplication

• It determines the magnitude
