In mathematics, an operand is the object of a mathematical operation, a quantity on which an operation is performed.
The following arithmetic expression shows an example of operators and operands:
In the above example, '+' is the symbol for the operation called addition.
The operand '3' is one of the inputs (quantities) followed by the addition operator, and the operand '6' is the other input necessary for the operation.
The result of the operation is 9. (The number '9' is also called the sum of the addends, 3 and 6.)
An operand, then, is also referred to as "one of the inputs (quantities) for an operation".
Operands may be complex, and may consist of expressions also made up of operators with operands.
In the above expression '(3 + 5)' is the first operand for the multiplication operator and '2' the second. The operand '(3 + 5)' is an expression in itself, which contains an addition operator, with the operands '3' and '5'.
Rules of precedence affect which values form operands for which operators:
When I try to remember the beginning
The whole thing comes like a dream
That don’t bring me laughs
And something might be reality
CHORUS
The nothing , the empty
Without light
Without a way
I still have regards
From what I’ve been but, who am I?
Prisoner of one life that
I don’t know the past
(CHORUS)
Due to scare of what I’ve been
Today I hide myself in darkness
Catching the few that rest
Waiting for the end of the line
(REPEAT)
When I’ll find what I think it’s real
To quench my thirsty for the truth
Finishing my sufferings and fears
Ahead of me like a thick haze
(CHORUS)
When I try to remember the beginning
The whole thing comes like a dream
That don’t bring me laughs
