Answer 2

Let's solve each of the given expressions step by step:

1. (-128):(-4):(-8):2 = ? To simplify this expression, we follow the order of operations (PEMDAS/BODMAS): (-128):(-4) means -128 divided by -4, which equals 32. Then, 32:(-8) means 32 divided by -8, which equals -4. Finally, -4:2 means -4 divided by 2, which equals -2.

Answer: -2

2. (-3)^3:(-3)^2+(-2)^3:(-1)^4-(-1)^8:(-1)^7 = ? To simplify this expression, we calculate the exponents first: (-3)^3 = -27 (-3)^2 = 9 (-2)^3 = -8 (-1)^4 = 1 (-1)^8 = 1 (-1)^7 = -1

Now we substitute the values: -27:9 + (-8):1 - 1:-1

Next, we perform the divisions: -3 + (-8) + 1

Finally, we add the numbers together: -3 + (-8) + 1 = -10

Answer: -10

3. -72 * 18 + 36 * (-4) = ? Simply apply the operations from left to right: -72 * 18 = -1296 36 * (-4) = -144

Now add the results together: -1296 + (-144) = -1440

Answer: -1440

4. (54 * (-25) + 44 * 25) : 50 = ? Perform the multiplications first: 54 * (-25) = -1350 44 * 25 = 1100

Now, add the results together: -1350 + 1100 = -250

Finally, divide the sum by 50: -250 : 50 = -5

Answer: -5

5. (-69 + 44) : (-5) = ? Perform the addition inside the parentheses: -69 + 44 = -25

Finally, divide by -5: -25 : (-5) = 5

Answer: 5

6. (-12) * 5 + (-54) : 3 - (-84 : (-14)) = ? First, perform the multiplication and division from left to right: (-12) * 5 = -60 (-54) : 3 = -18 (-84) : (-14) = 6 (the negative signs cancel each other out)

Now, substitute the results back into the expression: -60 + (-18) - 6

Next, add and subtract from left to right: -60 + (-18) = -78 -78 - 6 = -84

Answer: -84

7. (28 * (-12) - 28 * (-2)) : 14 = ? Perform the multiplications inside the parentheses first: 28 * (-12) = -336 28 * (-2) = -56

Now, subtract the results: -336 - (-56) = -336 + 56 = -280

Finally, divide by 14: -280 : 14 = -20

Answer: -20

8. 72.09 : (-9) + (-3.2) * 5 = ? First, divide 72.09 by (-9): 72.09 : (-9) = -8.01

Now, perform the multiplication: (-3.2) * 5 = -16

Finally, add the results together: -8.01 + (-16) = -24.01

Answer: -24.01
