Here they are -= and +=. What do they mean?

Here is the spiel:
a += b Roughly equivalent to a = a + b
a -= b Roughly equivalent to a = a - b
a *= b Roughly equivalent to a = a * b
a /= b Roughly equivalent to a = a / b
a //= b Roughly equivalent to a = a // b
a %= b Roughly equivalent to a = a % b
a **= b Roughly equivalent to a = a ** b
a &= b Roughly equivalent to a = a & b
a |= b Roughly equivalent to a = a | b
a ^= b Roughly equivalent to a = a ^ b
a >>= b Roughly equivalent to a = a >> b
a <<= b Roughly equivalent to a = a << b rysin commented: Helped a lot, answered question. +1

Thanks Sneekula, I got it now!

Here is the spiel:
a += b Roughly equivalent to a = a + b a -= b Roughly equivalent to a = a - b a *= b Roughly equivalent to a = a * b a /= b Roughly equivalent to a = a / b a //= b Roughly equivalent to a = a // b a %= b Roughly equivalent to a = a % b a **= b Roughly equivalent to a = a ** b a &= b Roughly equivalent to a = a & b a |= b Roughly equivalent to a = a | b a ^= b Roughly equivalent to a = a ^ b a >>= b Roughly equivalent to a = a >> b a <<= b Roughly equivalent to a = a << b
What do you mean "Roughly equivalent"? a += b is the exact same thing as a = a + b .

Just like in C, a += b does the same thing as a = a + b, but the code produced is more efficient. So, I think, the roughly is there for the sticklers in life.
