Adding and Subtracting
Adding and Subtracting:
Like signs add and stay with the sign
-4-3=-7
360+420= 780
-25-92=-117
Add and Subtract:
Unlike signs subtract stay with the sign of the higher integer
-3+4=1
-9+1=-8
39+(-29)= 10
Multiplying and Diving
Multiplying and Dividing:
Like signs stay positive
-4 x-3=12
-5/-25=5
4 x 7= 28
Multiplying and Dividing:
Unlike signs x or / and the answer is negative
-3 x 4= -12
-56/8= -7
6 x -4= -24
