Answer 3

The expression 20 + 200 - 200 - 20 + 7 can be simplified by performing the addition and subtraction operations from left to right.

Starting with 20 + 200, we get 220.

Next, subtracting 200 from 220 gives us 20.

Then, subtracting 20 from 20 results in 0.

Finally, adding 7 to 0 gives us 7.

Therefore, the answer to the expression is 7.
