WEIRD Mathematical System

In a "WEIRD" Mathematical system, the following is true:
11+1=1
11+2=2
5+2=2
3+5=8
5+10=4
12+9=10
9+8=6
18+28=2
27+13=7
10+9=8
11+11=11
33+7=7
22+16=5
15+12=5
15+7=11
23+10=11
22+1=1
35+12=3
These are clues!

After figuring out the system answer this problem: 152+46=?

It can be a combination of anything, like for example it can be 11+1-11=1 or any other combo!
it can be division, suntraction addition, multiplication, and etc.
