Use the associative law to add these integers.
(i) 200+(-33) +(-67)
(ii) 1022+(-663) +(-922) + 333
(iii) 1+(-325)+(-325) +650 + 1000
(iv) 0+(-1)+(1) +932+(-332)
(V) 230 +(-89) + 170 +(-11)+ 0
(vi) 911 +89+(-56)+(-44) ​

Answer 1

[(-) (+) = (-)]

[(-) (-) = (+)]

(i) 200+(-33) +(-67)

200 + (- 100)

100

(ii) 1022+(-663) +(-922) + 333

1022 + 333 +(-663 + 922)

1355 - 1585

-230

(iii) 1+(-325)+(-325) +650 + 1000

1 + 1000 + 650 - 650

1001

(iv) 0+(-1)+(1) +932+(-332)

932 + 1 - 332 - 1

600

(v)230 +(-89) + 170 +(-11)+ 0

230 + 170 - 89 - 11

300

(vi)911 +89+(-56)+(-44)

911 +89+-56 -44

900
