Integer Operations and Strategies

This tutorial teaches how to solve expressions with multiple negative and positive integers. It covers identifying integers with the same sign, combining them, and finding the difference between absolute values when signs differ. The tutorial includes three examples demonstrating these techniques, emphasizing grouping and using the number line for visualization.

What is the first step in solving expressions with multiple negatives and positives?

• Identify integers with the same sign

• Add all integers together

• Identify integers with different signs

• Subtract all integers

When grouping negative integers, what operation is performed on their absolute values?

• Subtraction

• Multiplication

• Addition

• Division

What is the sum of negative integers -12, -9, and -3?

• -21

• -30

• -15

• -24

How do you determine the final sign of the result when combining sums of different signs?

• Always use a negative sign

• Always use a positive sign

• Use the sign of the larger absolute value

• Use the sign of the smaller absolute value
