According to the order of operations, multiplication and division are performed before addition and subtraction. So, we first calculate 100 x 0, which is 0. Then, we add and subtract the remaining numbers, from left to right.

```

90 + 218 - 100 x 0 + 2 + 10 + 100

= 90 + 218 + 0 + 2 + 10 + 100

= 420

```

Therefore, the answer is **420**.
