Unary operations	-a	change the sign of a
Unary operations	~a	bitwise NOT a
Unary operations	++a	add 1 to a (before using a)
Unary operations	a++	add 1 to a (after using a)
Unary operations	--a	subtract 1 from a (before using a)
Unary operations	a--	subtract 1 from a (after using a)
Binary operations	a * b	multiply a by b
Binary operations	a / b	divide a by b
Binary operations	a % b	find the remainder of division of a by b	13 % 5 Returns 3
Binary operations	a + b	add a and b
Binary operations	a - b	subtract b from a
Binary operations	a & b	bitwise a AND b
Binary operations	a | b	bitwise a OR b
Binary operations	a ^ b	bitwise a XOR b
Bitwise	a << b	shift a by b bits to the left (padding with zeros)	9<<2 yields thirty-six, because 1001 shifted two bits to the left becomes 100100, which is thirty-six
Bitwise	a >> b	shift a by b bits to the right (copying the sign bit)	9>>2 yields two, because 1001 shifted two bits to the right becomes 10, which is two
Bitwise	a >>> b	shift a by b bits to the right (padding with zeros)	19>>>2 yields four, because 10011 shifted two bits to the right becomes 100, which is four. For non-negative numbers, zero-fill right shift and sign-propagating right shift yield the same result
Bitwise	a & b	AND: Returns a one in each bit position if bits of both operands are ones	15 & 9 yields 9 (1111 & 1001 = 1001)
Bitwise	a	b	OR: Returns a one in a bit if bits of either operand is one
Bitwise	a ^ b	XOR: Returns a one in a bit position if bits of one but not both operands are one	15 ^ 9 yields 6 (1111 ^ 1001 = 0110)
Bitwise	~ a	NOT: Flips the bits of its operand
