## What is the smallest negative number?

The smallest negative number is a 1 followed by 31 zeros which is interpreted as −231. Because twos’ complement is essentially arithmetic modulo 232, it would be equally logical to interpret it as 231. The negative value is chosen so that the negative integers are precisely those with a 1 as the most significant bit.

## Do numbers end?

The sequence of natural numbers never ends, and is infinite. There’s no reason why the 3s should ever stop: they repeat infinitely. So, when we see a number like “0.999…” (i.e. a decimal number with an infinite series of 9s), there is no end to the number of 9s.

## What is the smallest number in the world?
