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)= 94 = 5
11+8= 118 = 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
