subtrahend

If the minuend is less than the subtrahend, the difference will be a negative number.

Then the subtrahend (the number being subtracted) was dialed in.

Subtraction is done by adding the ten's complement of the subtrahend.

Place the minuend 4231 on top, the subtrahend 789 on the bottom.

Note that the same sum over the trivial roots gives the last subtrahend in the formula.

However, the 10 is not taken by reducing the minuend, rather one augments the subtrahend.

For example, the "subtract" subroutine had to form the one's complement of the subtrahend and add it.

Starting with a least significant digit, a subtraction of subtrahend:

The minuend is 704, the subtrahend is 512.

In situation in which no borrowing is needed, one only needs to take the number of rods in the subtrahend from the minuend.

To subtract, the operator was expected to mentally subtract 1 from the subtrahend and enter the result using the smaller digits.

Lower the carriage to its default position and then set the subtrahend onto the input sliders and turn the execution lever once.

If two's complement representation is used, subtraction requires only inverting the bits of the subtrahend and setting a carry into the rightmost bit.

Since subtracting 1 before complementing is equivalent to adding 1 afterwards, the operator would thus effectively add the ten's complement of the subtrahend.

If the subtrahend has fewer digits than the minuend, leading zeros must be added which will become leading nines when the complement is taken.

Since there was no subtraction instruction, only the twos-complement add (TAD), computing the difference of two operands required first negating the subtrahend.

The subtractor is best understood by considering that the subtrahend and both borrow bits have negative weights, whereas the X and D bits are positive.

The first number (5 in the previous example) is formally defined as the minuend and the second number (3 in the previous example) as the subtrahend.

The slat was then moved to expose the black digits (which now displayed the nines' complement of the subtrahend) and the minuend was added by dialing it in.

Where the subtrahend and the dividend segment differ, cross out the dividend digit and write if necessary the subtrahend digit and next vertical empty space.

Continuing the example of 86 39, the first variation attempts to subtract 9 from 6, and then 9 from 16, borrowing a 10 by marking near the digit of the subtrahend in the next column.

Thus in 1678, the publication of Caspar Questel's De pulvinari morientibus non subtrahend, ("On the pillow of which the dying should not be deprived"), initiated debate on the topic.

To subtract a number y (the subtrahend) from another number x (the minuend), the radix complement of y is added to x and the initial '1' of the result is discarded.

Using ones' complement representation requires inverting the bits of the subtrahend and connecting the carry out of the most significant bit to the carry in of the least significant bit (end-around carry).
