We use the commas to our advantage in most country commas is used instead of a full stop. I.E 3,5 can be (three and the half) so to solve this question now that will be 11,3 +15,7+3 equal 30. BAM

it's a trick question wants you to think out of the box break up the numbers in decimal points like.... 15.+9.1+5.9=30

Demigods666:
No possible answer because the sum of an odd number of odd numbers always results in an odd number.

Except by using trick method aka fraud method

Using factorial style:

11 + 3! (3*2*1, which equals 6) + 13 = 30

By the way, what kind of math problem is this self

You can use comma as decimal point.
