NumberWiz sum 445

It's been a long time since I challenged readers with a sum from the NumberWiz game. 

Here's a sum:
Using addition, subtraction, multiplication and division, how do you make 445 out of these six numbers 2, 5, 25, 50, 75, 100 ?

You're welcome to mail your solution to admin at proctele.se, or in the comments below.

Remember: You can buy NumberWiz in the App Store for half the price of a cup of coffee and generate as many sums as you like.
