Adding and Subtracting Rules. When adding or subtracting numbers that have the same sign, you add the numbers together and keep the sign = 8 7.

 Two Rules: 1. To add numbers with the same sign, ADD the absolute values and the answer has the same sign as the original numbers.  EXAMPLE:

Quick Start Expectations 1.Fill in planner and HWRS AN p #24-29, 61-62, 66 a-d (Show your work! by writing out number sentences and changing the signs to addition. NO calculator! ) 2. Get a signature on your HWRS No signature = zero points! 3. On desk: math journal, HWRS, pencil and pen 4. Warm Up: Give three examples of Additive Inverses: Possible answers: ‾ 1, ,000 = ‾9.837 = 0 ‾ ⅜ + ⅜ = 0 Additive Inverses: Two numbers, when added together, equal 0.

Same signs Different signs Change a subtraction expression to an addition by adding the opposite of the second number. Remember: “Don’t subtract… add the opposite”

Remember: “Don’t subtract… add the opposite”

-10 – – 5 = -15 = = 15

No No! Subtraction is NOT commutative! because you can’t change the order and get the same answer.

a.The thermometer reads – 4°F when Allison checks it in the morning and + 7°F when she checks it at noon. What is the change in temperature over the course of the morning?

b. Stephanie spends $20 to buy ingredients for baked goods to sell at the bake sale. Her profit is $30. How much does she sell her baked goods for? Or: Matt writes a check for $20. Then he makes a deposit. He ends up with $30 more than he had before writing the check. How much does he deposit?

c.In Math Fever, Jacob answered his first two questions incorrectly. The second question was worth 150 points. His current score is – 450. What was the point value of his first question?
