Let's solve the expression step by step:

\[
1 + 1 + 1 + 1 + 55 - 522 + 5 \times 45
\]

First, handle the multiplication:

\[
5 \times 45 = 225
\]

Now, substitute this back into the expression:

\[
1 + 1 + 1 + 1 + 55 - 522 + 225
\]

Next, add and subtract from left to right:

\[
1 + 1 = 2
\]

\[
2 + 1 = 3
\]

\[
3 + 1 = 4
\]

\[
4 + 55 = 59
\]

\[
59 - 522 = -463
\]

\[
-463 + 225 = -238
\]

So, the final answer is:

\[
\boxed{-238}
\]
