 ADDING INTEGERS THAT HAVE SAME SIGN, both (-) or both (+) ADD NUMBERS AS IF NO SIGN PRESENT. PUT THE (-) OR (+) SIGN FROM THE PROBLEM. ADD LIKE SIGNS EXAMPLE: +6+(+5)= ? -4+(-8)= ? ADD LIKE SIGNS ANSWER: +6+(+5)= +11 -4+(-8)= -12 ADDING POSITIVE INTEGERS & NEGATIVE INTEGERS IGNORE SIGNS; SUBTRACT THE SMALLER FROM LARGER. USE SIGN OF NUMBER THAT WAS FARTHER FROM 0. (larger) ADDITION OF UNLIKE SIGNS: +9+(-4)= ? -11+8= ? +9+(-4)= 9-4 = 5 -11+8= 11-8 = 3 SUBTRACTING POSITIVE & NEGATIVE INTEGERS 1.FIND THE OPPOSITE OF NUMBER BEING SUBTRACTED. 2. REWRITE PROBLEM AS AN ADDITION. 3. FIND ANSWER SUBTRACTING POSITIVE & NEGATIVE INTEGERS EXAMPLE: +7-(+4)= ? +9-(-10)= ? +7-(+4)= +7+(-4)= 3 +9-(-10)= +9+(+10)= 19 SUBTRACTING POSITIVE & NEGATIVE INTEGERS EXAMPLE: -5-(-10)= ? +3-(+8)= ? -5-(-10)= -5+(10)= 5 +3-(+8)= +3+(-8)= -5 MULTIPLYING LIKE SIGNS PRODUCT OF LIKE SIGNS IS ALWAYS POSITIVE.(+) (-).(-)= + (+).(+)= + MULTIPLYING LIKE SIGNS EXAMPLE: (+5)*(+8)=? (-9)*(-7)=? (+5)*(+8)= +40 (-9)*(-7)= +63 DIVIDING LIKE SIGNS QUOTIENT OF LIKE SIGNS IS POSITIVE. (+) DIVIDING LIKE SIGNS EXAMPLE: +12÷(+3)= ? -35÷(-5)= ? +12÷(+3)= +4 -35÷(-5)= +7 DIVIDING UNLIKE SIGNS QUOTIENT OF UNLIKE SIGNS, ONE POSITIVE & ONE NEGATIVE, IS NEGATIVE. (-) DIVIDING UNLIKE SIGNS EXAMPLE: +30÷(-5)= ? -48÷(+6)= ? -6 -8 MULTIPLYING UNLIKE SIGNS PRODUCT OF UNLIKE SIGNS IS NEGATIVE (-) MULTIPLYING UNLIKE SIGNS EXAMPLE: +6*(-9)= ? -7*(+6)= ? +6*(-9)= -54 -7*(+6)= -42
