Answer 2

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

20 - 5 + 11(30 - 2) - 7 ± 33 + 33 - 11 + 333 - 116 + 33

First, let's simplify the inner parentheses:

= 20 - 5 + 11(28) - 7 ± 33 + 33 - 11 + 333 - 116 + 33

Next, let's perform the multiplication:

= 20 - 5 + 308 - 7 ± 33 + 33 - 11 + 333 - 116 + 33

Now, let's calculate the addition and subtraction from left to right:

= 15 + 308 - 7 ± 33 + 33 - 11 + 333 - 116 + 33

= 323 - 7 ± 33 + 33 - 11 + 333 - 116 + 33

= 316 ± 33 + 33 - 11 + 333 - 116 + 33

= 316 ± 66 - 11 + 333 - 116 + 33

= 382 ± 11 + 333 - 116 + 33

= 371 ± 333 - 116 + 33

= 704 ± 116 + 33

Now, let's consider the ± symbol. If we take the positive value:

= 704 + 116 + 33

= 820 + 33

= 853

If we take the negative value:

= 704 - 116 + 33

= 588 + 33

= 621

Therefore, the two possible results are 853 and 621, depending on whether you take the positive or negative value with the ± symbol.
