How to solve this integers?
Q2. i) -2 x 3 x -4
-2 x 3= -6
-6 x -4= 24 (negative and negative is positive)
ii)2 x -5 x -6
2 x -5= -10
-10 x -6= 60(negative and negative is positive)
iv) 8 x 7 x -10
8 x 7= 56
56 x -10= -560(negative and positive is negative)
Q3 i) 18 x -27 x 30
18 x -27= -486
-486 x 30= -14580
iii)-17 x -23 x 41
-17 x -23=391(negative and negative is positive)
391 x 41= 16031
Q4. i) 18 x [9+(-7)]= 18 x 9 + 18 x (-7) [distributive property]
[9+(-7] will become [9-7] (negative and positive is negative)
18 x [9-7]
18 x 2= 36 = 18 x 9 + 18 x -7
18 x 2= 36 = 162 + (-126)
36 = 162 - 126(negative and positive is negative)
36 = 36
Hence, Verified
