Which input component in a subtractor signifies the quantity to be deducted from a starting value?

In a subtractor operation, the component that signifies the quantity to be deducted from a starting value is known as the subtrahend. In a subtraction equation, the subtrahend is the number that is taken away from another number, which is typically referred to as the minuend.

For example, in the equation 10 - 3 = 7, 10 is the minuend (the starting value) and 3 is the subtrahend (the quantity being deducted). Understanding this distinction is crucial for performing and interpreting subtraction, as the subtrahend directly indicates how much is being reduced from the initial value.

The other components mentioned play different roles in arithmetic operations, with the minuend providing the original value and the addend relating to addition, which does not pertain to subtraction directly. Borrowing is a concept used during the subtraction process when more complex numbers are involved, but it does not define a specific component of the operation itself.
