Not sure if this is too hard, but it's a more or less simple math puzzle. Use the numbers
to get an answer of 1150. You can use the operators
You can use each number only once, each operator can be used as many times as you want. You can also round to the nearest 10. You also cannot put the numbers together(e.g. you can't do 1234 or such, each has to be a separate number). In addition, all numbers must be used.
Note: This is solvable, no lateral thinking needed. Pure calculations.
