NumberWiz sum 850

Hi NumberWiz friends! Spring has finally arrived in Skåne, the southernmost tip of Sweden. It's welcome after a long and coooold Winter, which was even longer and colder than last year.

We've had spring for a few days already, but I only mention it now, so as to avoid risk.

Here's another spring sum I collected from the NumberWiz app.

How do you add, subtract, multiply and divide 1 5 7 10 10 25 to get 850 ?
