Integers

Adding and Subtracting


  • When having like signs you need to add and stay with the sign.


-6 - 12= -18


-15-10=- 25


-14-6= -20


  • When you have unlike signs, subtract and stay with the sign of the higher integer.



-12+15= 3


17+ (-25)= -8


-4+10= 6




Multiplying and Dividing.


  • Like signs they stay positive and multiply or divide.


-2 x -2 = 4


5 x 2 = 10


-3 x -4 = 12




  • Unlike signs x or / and the answer is negative.



-6/2= -3


21/-3= -7


-32/ (8)= -4
