this is pretty hard to translate, but I think I understand it...
"Woman: My husband is too strict...
For him, 1 plus 1 equals 1.
Do you know what I mean?
If he says something is one way, it MUST be that way.
so it's pretty uncomprehensible how I wrote it so please write it another way, but I think you can understand what she's saying. she's describing her husband as someone who is close-minded and stubborn and doesn't make room for new opinions and information.
still... no context? that's pretty strange. I suppose it must be a random NPC.
