Answer 5

it mean decrease and equal to a normal minus sigh

Answer 6

If you have int x = 10; int y;

y = x-=3;

Console.WriteLine(y);

This will output basically 10 - 3 = 7.

The same thing is if we would have y = x+=3; This will output 10 + 3 = 13.

Just as you said it's basically y = x + 3 or y = x - 3

Hope this helps! >^.^<
