Answer 2

1) To solve the expression (1) +(6*(-7)+51):(-3)-78, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, let's simplify the expression within the parentheses: 6 * (-7) = -42

Now, we can rewrite the expression: (1) + (-42 + 51) / (-3) - 78

Next, we perform the addition and subtraction from left to right: 1 + 9 / (-3) - 78

Now, let's simplify the division: 9 / (-3) = -3

Finally, perform the addition and subtraction from left to right: 1 - 3 - 78 = -80

Therefore, the value of the expression (1) +(6*(-7)+51):(-3)-78 is -80.

2) To solve the expression (2) +(19-75):(-2-3*2), we again follow the order of operations:

First, simplify the expression within the parentheses: -3 * 2 = -6

Next, we rewrite the expression: (2) + (19 - 75) / (-2 - (-6))

Now, perform the addition and subtraction from left to right: 2 + (-56) / (-2 + 6)

Simplify the expression within the parentheses: -2 + 6 = 4

Now, we have: 2 + (-56) / 4

Finally, perform the division: -56 / 4 = -14

Now, add the remaining terms: 2 + (-14) = -12

Therefore, the value of the expression (2) +(19-75):(-2-3*2) is -12.

3) To solve the expression (3) +-6*8+25+14:(-2), we follow the order of operations:

First, perform the multiplication: -6 * 8 = -48

Now, rewrite the expression: -48 + 25 + 14 / (-2)

Next, perform the division: 14 / (-2) = -7

Now, we have: -48 + 25 + (-7)

Finally, perform the addition and subtraction from left to right: -48 + 25 - 7 = -30

Therefore, the value of the expression (3) +-6*8+25+14:(-2) is -30.

4) To solve the expression (4) +-38-46-90:((-2)*5), we follow the order of operations:

First, perform the multiplication: (-2) * 5 = -10

Now, rewrite the expression: -38 - 46 - 90 / (-10)

Next, perform the division: 90 / (-10) = -9

Now, we have: -38 - 46 - (-9)

To simplify the expression, we can rewrite the subtraction of a negative number as addition: -38 - 46 + 9

Finally, perform the addition and subtraction from left to right: -38 - 46 + 9 = -75

Therefore, the value of the expression (4) +-38-46-90:((-2)*5) is -75.

5) To solve the expression (5) +-97-(-19-9):4*2, we follow the order of operations:

First, perform the subtraction within the parentheses: -19 - 9 = -28

Now, rewrite the expression: -97 - (-28) / (4 * 2)

Next, we perform the division and multiplication from left to right: -97 - (-28) / 8

To simplify the subtraction of a negative number as addition: -97 + 28 / 8

Now, perform the division: 28 / 8 = 3.5

Finally, perform the addition and subtraction from left to right: -97 + 3.5 = -93.5

Therefore, the value of the expression (5) +-97-(-19-9):4*2 is -93.5.

6) To solve the expression (6) +(-14-72:(-9))*(-2-2), we follow the order of operations:

First, perform the division within the parentheses: 72 / (-9) = -8

Next, rewrite the expression: -14 - (-8) * (-2 - 2)

Now, perform the subtraction within the parentheses: -2 - 2 = -4

Now, we have: -14 - (-8) * (-4)

To simplify the subtraction of a negative number as addition: -14 + 8 * (-4)

Now, perform the multiplication: 8 * (-4) = -32

Finally, perform the addition and subtraction from left to right: -14 + (-32) = -46

Therefore, the value of the expression (6) +(-14-72:(-9))*(-2-2) is -46.

7) To solve the expression (7) +(-83+(-6-15:5))*(-6), we follow the order of operations:

First, perform the division within the parentheses: 15 / 5 = 3

Next, perform the addition and subtraction within the parentheses: (-6) - 3 = -9

Now, rewrite the expression: -83 + (-9) * (-6)

Now, perform the multiplication: (-9) * (-6) = 54

Finally, perform the addition and subtraction from left to right: -83 + 54 = -29

Therefore, the value of the expression (7) +(-83+(-6-15:5))*(-6) is -29.

8) To solve the expression (8) +(-47+6*(-6)+27):(+8), we follow the order of operations:

First, perform the multiplication: 6 * (-6) = -36

Now, rewrite the expression: (-47) + (-36) + 27 / 8

Next, perform the division: 27 / 8 = 3.375

Now, we have: (-47) + (-36) + 3.375

Finally, perform the addition and subtraction from left to right: (-47) + (-36) + 3.375 = -79.625

Therefore, the value of the expression (8) +(-47+6*(-6)+27):(+8) is -79.625.

9) To solve the expression (9) +8:(-2)*9+17-48, we follow the order of operations:

First, perform the division: 8 / (-2) = -4

Now, rewrite the expression: (-4) * 9 + 17 - 48

Next, perform the multiplication: (-4) * 9 = -36

Now, we have: -36 + 17 - 48

Finally, perform the addition and subtraction from left to right: -36 + 17 - 48 = -67

Therefore, the value of the expression (9) +8:(-2)*9+17-48 is -67.

10) To solve the expression (10) +32-(-9*3-8):(-7), we follow the order of operations:

First, perform the multiplication: 9 * 3 = 27

Now, rewrite the expression: 32 - (27 - 8) / (-7)

Next, perform the subtraction within the parentheses: 27 - 8 = 19

Now, we have: 32 - 19 / (-7)

Now, perform the division: 19 / (-7) = -2.7142857142857144 (rounded to the nearest decimal place)

Finally, perform the addition and subtraction from left to right: 32 - (-2.7142857142857144) = 34.714285714285715

Therefore, the value of the expression (10) +32-(-9*3-8):(-7) is approximately 34.714.

Note: Please double-check the original problem and ensure there are no missing parentheses or operators.
