Answer:
-1,41,400
Step-by-step explanation:
-194 × 143 - 57 × 1994
-194 = (-200+6) , 143 = (150 - 7), 57 = (50 + 7) , 1994 = (2000 - 6)
=(-200+6) * (150 - 7) - [(50 + 7) * (2000 - 6)]
Using distributive law of multiplication,
= (-200 * 150) + (6 * 150) + (- 200 * -7) + (6 * -7) - [(50 * 2000) + (50 * -6) + (7 * 2000) + (7 * -6)]
= -30000 + 900 + 1400 - 42 -[100000 - 300 + 14000 - 42]
= -27,742 - [1,13,658]
= -1,41,400
