Answer»

Answer:

Here, we will use the following RULES,

(+)×(−)=(−)

(−)×(+)=(−)

(−)×(−)=(+)

(+)×(+)=(+)

(a)26×(−48)+(−48)×(−36)=−48(26−36)=−48×−10=480

(b)8×53×(−125)=(−125×8)×53=−1000×53=−53000

(C)15×(−25)×(−4)×(−10)=100×(−150)=−15000

(d)(−41)×102=(−40−1)×(100+2)=−4000−80−100−2=−4182

(E)625×(−35)+(−625)×65=625×(−35−65)=625×(−100)=62500

(F)7×(50−2)=750−14=736

(g)(−17)×(−29)=(−20+3)×(−30+1)=600−20−90+3=493

(h)(−57)×(−19)+57=−57(−19−1)=−57×(−20)=1140
