Answers
Given :-
a = -4, b = -6, c = 7, d = -10
Question(s) :-
1) 2c - 1
=> 2 × 7 - 1 => 14 - 1 = 13
2) b + c
=> -6 + 7 = 1
3) -2b
=> -2 × -6 = 12
4) b - d + 1
=> -6 - (-10) + 1 => -6 + 10 + 1 => -6 + 11 = 5
1) d ÷ -2
=> -10 ÷ -2 = 5
2) 2c
=> 2 × 7 = 14
3) -2b - 5
=> -2 × -6 - 5 => 12 - 5 = 7
4) c - 2a - 3
=> 7 - 2 × -4 - 3 => 7 + 8 - 3 => 15 - 3 = 12
5) d + 2a + 3
=> -10 + 2 × -4 + 3 => -10 - 8 + 3 => -18 + 3 = -15
6) -3a + 2
=> -3 × -4 + 2 => 12 + 2 = 14
7) b - d
=> -6 - (-10) => -6 + 10 = 4
1) 8c + 5d
=> 8 × 7 + 5 × -10 => 56 + (-50) => 56 - 50 = 6
2) -3a - b - 3
=> -3 × -4 - (-6) - 3 => 12 + 6 - 3 => 18 - 3 = 15
3) -2d + a - 1
=> -2 × -10 + (-4) - 1 => 20 - 4 - 1 => 20 - 5 = 15
4) 5c + 2d - b - 1
=> 5 × 7 + 2 × -10 - (-6) - 1 => 35 - 20 + 6 - 1
=> 35 + 6 - 20 - 1 => 41 - 21 = 20
5) a - b
=> -4 - (-6) => -4 + 6 = 2
6) 6c + 3a + 5b + 1
=> 6 × 7 + 3 × -4 + 5 × -6 + 1 => 42 + (-12) + (-30) + 1
=> 42 + 1 - 12 - 30 => 43 - 42 = 1
7) -3d + 3b
=> -3 × -10 + 3 × -6 => 30 + (-18) => 30 - 18 = 12
8) 4c + d + b
=> 4 × 7 + (-10) + (-6) => 28 - 10 - 6 => 28 - 16 = 12
1) 5b - 4d - c
=> 5 × -6 - 4 × -10 - 7 => -30 + 40 - 7 => 40 - 30 - 7
=> 40 - 37 = 3
2) -7a - 2c + 1
=> -7 × -4 - 2 × 7 + 1 => 28 - 14 + 1 => 28 + 1 - 14
=> 29 - 14 = 15
8) 2b + 3c - d - c
=> 2 × -6 + 3 × 7 - (-10) - 7 => -12 + 21 + 10 - 7
=> 21 + 10 - 12 - 7 => 31 - 19 = 12
3) 4d - 7b - a - 1
=> 4 × -10 - 7 × -6 - 4 - 1 => -40 + 42 - 5 => 42 - 40 - 5
=> 42 - 45 = -3
4) 5a - 2b + b + 2c + a + 1
=> 5 × -4 - 2 × -6 + (-6) + 2 × -6 + (-4) + 1
=> -20 + 12 - 6 - 12 - 4 + 1 => 12 + 1 - 20 - 12 - 6 - 4
=> 13 - 44 = -31
5) 6c - 2b + 10a
=> 6 × 7 - 2 × -6 + 10 × -4 => 42 + 12 - 40 => 54 - 40 = 14
