# Basic Math Integers

 Integer is a A. Fraction B. Negative Number C. Decimal or Percent D. Postive Number E. Both B and D Interger is E, a Negative or Postive Whole Number When Adding, Subtracting, or multiplying an Integer, you always get an Integer as an answer A. True B. False A. True.  When Adding, subtracting or multiplying an Integer, you ALWAYS get an integer as the answer.-3*11= -33-3 + 4= +1 or 1Remember an Integer is a Postive or Negative WHOLE number (not a fraction or percent, or decimal). When dividing an Integer, you always get an Integer as the answer. A. True B. False B. False.  It is possible to get a fraction, or decimal when dividing with a integer.8/5 (8 divided by 5) = 1.6 Example Card: When adding and subtracting with Negative Integers, imagine a line that moves left and right, with 0 as the center, negative numbers to the left of zero, positive numbers to the right of zero. ____________________0_______________________-10   -5  -4  -3  -2  -1             1  2  3  4  5      10        20 Adding a postive number moves to the right-3 plus 4 equals positive 1     Example Card Adding a positive number to a negative integer moves the number to the right. -3 plus 6 equals postive 3 (-3+6=3) -10 plus 5 equals negative 5 (-10+5= -5) ____________________0_______________________-10   -5  -4  -3  -2  -1             1  2  3  4  5      10        20 -3 plus postive 6, move 6 sports to the right, to positive 3. -10 plus positive 5, move 5 spots to the right, to negative 5.   Example Card Subtracting a postive number moves to the left. 4 minus 3 equals 1 (4-3=1) -3 minus 5 equals negative 8 (-3 - 5= -8) 3 minus 5 equals negative 2 __________________ 0________________-10 -9 -8-7-6-5-4-3-2-1  1 2 3 4 5 6 7 8 9 10 4 minus 3 (postive 4, move left 3 spaces, to postive 1)-3 minus 5 (negative 3, move 5 spaces left, to negative 8)3 minus 5 (postive 3, moves 5 spaces left, to negative 2) Example Card When adding a Negative number, move left: Postive 4 plus Negative 3 equals postive 1. 4 + -3= 1 Negative 3 plus Negative 2 equals Negative 5. -3 + -2= -5. ______________________0_______________________-10-9-8-7-6  -5  -4 -3 -2  -1    1  2  3  4  5  6  7  8  9  10 4 + -3 (Postive 4, move left 3 spaces to postive 1)-3 + -2 (Negative 3, move left 2 spaces to Negative 5).  Example Card When subtracting a Negative Number, move right: Positive 1 minus Negative 2 equals postive 3 1 - -2= 3 (subtracting a negative is like addition) Negative 2 minus Negative 3 equals 1 -2 minus -3= 1 ____________________0_____________________-10 -9 -8-7-6 -5 -4 -3-2-1   1 2 3 4 5 6 7 8 9 101- -2 (postive 1, move right 2 spaces, to postive 3) -2 - -3 (negative 2, move right 2 spaces to postive 1) Multiply and Divide Integers: Step 1: Ignore Signs and do the problem Step 2:  A. If original signs match, the result in postive                   3*10=30, -5*-3=15, 24/8=3, -24/-8=3          B. If original signs don't match, the result is negative.              3*-10= -30, -5*-3= -15, -24/8=-3 Example Card in Front Authorhuskersoxfan ID181423 Card SetBasic Math Integers DescriptionInteger Rules Updated2012-11-03T18:37:51Z Show Answers
