I love my calculator, but something bad happened to it yesterday: It fell from the window.
When I ask some basic questions, my calculator gives me wrong numbers.
Here are the values:
What's $3\times7$?
= $2$
What's $5\times6$?
= $3$
What's $11\times5$?
= $5$
What's $4\times4$?
= $1$
What's wrong with my calculator? Why does it give these values?
Hint:
Its processor is running well
