27) 3 (-5) (-7)
When there is no math symbol between numbers it is multiplication.
Multiply from left to right:
3 * -5 = -15
-15 * -7 = 105
28) -2 * 2 (-3) *2 =
-2 *2 = -4
-4 * -3 = 12
12*2 = 24
31) A negative divided by a negative is positive:
-128 / -4 = 32
32 -36 / 2 / 24 /4
Divide the top and bottom first then divide those:
-36 / 2 = -18
24 / 4 = 6
-18 / 6 = -3
I think it is 4.5*10^(-4). It is because 10^(-4) is 10000. 10000*4.5 is 0.00045.

Subtracting a negative number is like removing debt. When you remove debt, you effectively gave someone money and the value of their bank account increased.
Another answer is that “subtraction is addition of the opposite,” so subtracting a negative number is really adding a positive number, which again causes the other number to increase.
