Answer :
Let's find each of the given products step-by-step.
(i) [tex]\( (-1) \times 385 \)[/tex]
Multiplying -1 by 385, we get:
[tex]\[ (-1) \times 385 = -385 \][/tex]
(ii) [tex]\( (-22) \times (-10) \times 9 \)[/tex]
First, we multiply -22 by -10:
[tex]\[ (-22) \times (-10) = 220 \][/tex]
Then multiply the result by 9:
[tex]\[ 220 \times 9 = 1980 \][/tex]
(iii) [tex]\( (-22) \times (-30) \)[/tex]
Multiplying -22 by -30:
[tex]\[ (-22) \times (-30) = 660 \][/tex]
(iv) [tex]\( (-15) \times (-8) \times 0 \)[/tex]
Multiplying anything by 0 gives 0:
[tex]\[ (-15) \times (-8) = 120 \][/tex]
[tex]\[ 120 \times 0 = 0 \][/tex]
(v) [tex]\( (-1) \times (-798) \)[/tex]
Multiplying -1 by -798:
[tex]\[ (-1) \times (-798) = 798 \][/tex]
(vi) [tex]\( (-30) \times (-2) \times (-5) \times 7 \)[/tex]
First, multiply -30 by -2:
[tex]\[ (-30) \times (-2) = 60 \][/tex]
Next, multiply the result by -5:
[tex]\[ 60 \times (-5) = -300 \][/tex]
Finally, multiply by 7:
[tex]\[ -300 \times 7 = -2100 \][/tex]
(vii) [tex]\( (-2) \times (-3) \times (-4) \times (-6) \)[/tex]
First, multiply -2 by -3:
[tex]\[ (-2) \times (-3) = 6 \][/tex]
Next, multiply by -4:
[tex]\[ 6 \times (-4) = -24 \][/tex]
Finally, multiply by -6:
[tex]\[ -24 \times (-6) = 144 \][/tex]
(viii) [tex]\( (-18) \times (-5) \times (-6) \)[/tex]
First, multiply -18 by -5:
[tex]\[ (-18) \times (-5) = 90 \][/tex]
Then multiply the result by -6:
[tex]\[ 90 \times (-6) = -540 \][/tex]
So, the solutions are:
1. [tex]\((-1) \times 385 = -385\)[/tex]
2. [tex]\((-22) \times (-10) \times 9 = 1980\)[/tex]
