Title: Addition of Integers with Like and Unlike Signs
Slide 1: Introduction - Welcome to our presentation on the addition of integers with like and unlike signs. - In this presentation, we will explore the rules and concepts related to adding integers with the same and different signs.
Slide 2: What are Integers? - Integers are whole numbers that can be positive, negative, or zero. - Examples of integers: -3, -2, -1, 0, 1, 2, 3, etc.
Slide 3: Addition of Integers with Like Signs - When adding integers with like signs (both positive or both negative), we add their absolute values and keep the common sign. - Example: (-5) + (-3) = -8
Slide 4: Addition of Integers with Unlike Signs - When adding integers with unlike signs (one positive and one negative), we subtract the smaller absolute value from the larger absolute value and keep the sign of the number with the larger absolute value. - Example: (-7) + 4 = -3
Slide 5: Visual Representation of Addition with Like Signs - Visual representation of adding integers with like signs using a number line. - Example: (+3) + (+2) = +5
Slide 6: Visual Representation of Addition with Unlike Signs - Visual representation of adding integers with unlike signs using a number line. - Example: (-4) + (+6) = +2
Slide 7: Rules for Adding Integers - Rule 1: When adding integers with like signs, add their absolute values and keep the common sign. - Rule 2: When adding integers with unlike signs, subtract the smaller absolute value from the larger absolute value and keep the sign of the number with the larger absolute value.
Slide 8: Examples - Example 1: (-9) + (-2) = -11 - Example 2: (+5) + (+7) = +12 - Example 3: (-8) + (+3) = -5 - Example 4: (+2) + (-6) = -4
Slide 9: Practice Questions - Provide a few practice questions for the audience to solve on their own or discuss in groups.
Slide 10: Summary - Addition of integers with like signs involves adding their absolute values and keeping the common sign. - Addition of integers with unlike signs involves subtracting the smaller absolute value from the larger absolute value and keeping the sign of the number with the larger absolute value.
Slide 11: Conclusion - We have explored the addition of integers with like and unlike signs. - Remember to follow the rules and concepts discussed to solve addition problems involving integers. - Thank you for your attention!
