Let's break down the calculation step by step.

First, calculate \( 35.7 \times 99 \):

\[ 35.7 \times 99 = 35.7 \times (100 - 1) = 35.7 \times 100 - 35.7 \times 1 \]
\[ = 3570 - 35.7 \]
\[ = 3534.3 \]

Next, add 35 to the result:

\[ 3534.3 + 35 = 3569.3 \]

Finally, add 0.7:

\[ 3569.3 + 0.7 = 3570 \]

So, the final result is:

\[ 35.7 \times 99 + 35 + 0.7 = 3570 \]
