$$36+18\times 3\times 4\times 5\times 6\times 7\times 8\times 9+1+2+3+4+5+6$$

Multiply 18 and 3 to get 54.

$$36+54\times 4\times 5\times 6\times 7\times 8\times 9+1+2+3+4+5+6$$

Multiply 54 and 4 to get 216.

$$36+216\times 5\times 6\times 7\times 8\times 9+1+2+3+4+5+6$$

Multiply 216 and 5 to get 1080.

$$36+1080\times 6\times 7\times 8\times 9+1+2+3+4+5+6$$

Multiply 1080 and 6 to get 6480.

$$36+6480\times 7\times 8\times 9+1+2+3+4+5+6$$

Multiply 6480 and 7 to get 45360.

$$36+45360\times 8\times 9+1+2+3+4+5+6$$

Multiply 45360 and 8 to get 362880.

$$36+362880\times 9+1+2+3+4+5+6$$
