Tricky math! Can you solve this? If 11+11=4 and 12+12=9 Then 13+13=?

Bubble boy marrow transplant

In 1983, David, the “the boy in the bubble,” underwent a bone marrow transplant operation in the hope that it could help him develop the immunity he had lacked all his life. He was born with a genetic disease, severe combined immune deficiency, (SCID). Thus, David Vetter spent his life protected, but isolated, in a sterile plastic “bubble.” The hope was that the bone marrow from his sister (four years older) would stimulate the growth of his immune system. The marrow was treated to cleanse it of germs, and was transferred in a fluid through a vein into David's bloodstream. Sadly an undetected Epstein Barr virus remained in it despite the treatment. By New Year's Day, he had a temperature of 99.5°F, indicating the onset of illness. Less than two months later, he died of Burkitt's lymphoma..«

Fish Heads

A customer at Green's Gourmet Grocery marveled at the proprietor's quick wit and intelligence.
"Tell me, Green, what makes you so smart?"
"I wouldn't share my secret with just anyone," Green replies, lowering his voice so the other shoppers won't hear. "But since you're a good and faithful customer, I'll let you in on it. Fish heads. You eat enough of them, you'll be positively brilliant."
"You sell them here?" the customer asks.
"Only $4 apiece," says Green.
The customer buys three. A week later, he's back in the store complaining that the fish heads were disgusting and he isn't any smarter.
"You didn't eat enough, " says Green. The customer goes home with 20 more fish heads. Two weeks later, he's back and this time he's really angry.
"Hey, Green," he says, "You're selling me fish heads for $4 apiece when I can buy the whole fish for $2. You're ripping me off!"

"You see?" says Green. "You're getting smarter already!"
