Answer 3

To solve this expression, let's break it down step by step:

(+7) • (-4) • (-8) • (-6) • (-42) : 264 : (-4)

First, let's deal with the multiplication operations:

7 • (-4) = -28 -28 • (-8) = 224 224 • (-6) = -1344 -1344 • (-42) = 56448

Now, the expression becomes:

56448 : 264 : (-4)

Next, divide 56448 by 264:

56448 ÷ 264 ≈ 214

The expression now becomes:

214 : (-4)

Finally, divide 214 by -4:

214 ÷ (-4) = -53.5

So, the final result is approximately -53.5.
