Adding integers

5+(-2)

5-2=3

-1+(-4)

-1+-4=-5

-6+(-2)

-6+-2=-8

-7+3

-7-3=-4

-8+3

-8-3=-5

Adding two negatives

step 1. add their absolute values

step 2. use their common sign as the sign of the sum

(adding two negatives the answer will be negative)

-2+(-21)

2+21=-21

(-3)+(-19)

3+19=-22

adding numbers with different signs

step 1 find the lager absolute value minus the smaller absolute value

step 2 use the sign of the number with the larger absolute value as the sign of the sum

-2+25

25-2=23

3+(-17)

17-3=14

-14 (negative because 17 is greater than 3)

-18+10

18-10=-8

(-3)+4+(-11)

4-3=1

1-11=-10

Subtracting

(write the subtraction problem as addition)

a-b=a+(-b)

-4-10

-4+(-10)=-14

6-(-5)

6+5=11

-11-(-7)

-11+7=-4

-3-(-4)

-3+4=1

-3-7=

-3+(-7)=-10
