Working with Integers

Fill in the blanks with the missing notes. An integer is any whole number that is positive or negative, or a number that is not a fraction or a decimal. Some examples of intergers include 12, -20, 1203, -1. Sort the numbers below into two categories: integers and not integers. Integers 1 -9 1023 -938503 222 121212 -924 -29349494 Not Integers .4 -.50 1 -5 1.39 2.01 1.99 -5.001 Fill in the missing blanks. Integers can be added, subtracted, multiplied, and divided. To help solve problems involving integers, you can memorize certain rules.Adding or subtracting the same signs results in an answer with the SAME sign.1. (+) + (+) = (+)ie. 7 + 1 = 8 (a POSITIVE number)2. (-) + (-) = (-)ie. -4 + -4 = -8Adding or subtracting with DIFFERENT signs results in an answer with the number MOST represented (or bigger).3. (+) + (-) = which ever sign has the bigger number.ie. 9 + -2 = 7 (7 is positive because the positive 9 is BIGGER than the 2. Also, adding a negative is like SUBTRACTING a number)4. (+) - (-) = The two (-) signs NEXT to each other results in a POSITIVE.ie. 9 - (-2) = is REALLY... 9 + 2 = 11When integers are multiplied...(+) x (+) = (+)(+) x (-) = (-)(-) x (-) = (+)When integers are divided...(+) / (+) = (+)(+) / (-) = (-)(-) / (-) = (+) Solve. 1. -9 + 5 = 2. 12 + 2 = 3. 9 - (-2) = 4. -10 - 2 = 5. -14 - 7 = Solve. 1. 4 x -2 =2. -12 x -12 = 3. -5 x -7 =4. 12 x 10 = 5. -9 / -3 = 6. 16 / -4 = 7. -20 / 5 = Create 3 of your own math problems adding and subtracting integers. Then, create three of your own math problems multiplying and dividing integers. 1. 2. 3. 1. 2. 3.
