Fascinating comparison of ant and human brains

An ant brain has about 250 000 brain cells.

Math is right, they apparently just don't know how much 10 billion is

250,000 brain cells
40,000 ants
10 Billion combined brain cells, or 10,000 Million

A billion is a number with two distinct definitions:

-- 1,000,000,000, i.e. one thousand million, or 109 (ten to the ninth power), as defined on the short scale. This is now the meaning in both British and American English.

-- 1,000,000,000,000, i.e. one million million, or 1012 (ten to the twelfth power), as defined on the long scale. This is one thousand times larger than the short scale billion, and equivalent to the short scale trillion. This is the historical meaning in English and the current use in many non-English-speaking countries where billion and trillion 1018 (ten to the eighteenth power) maintain their long scale definitions.

American English adopted the short scale definition from the French (it enjoyed usage in France at the time, alongside the long-scale definition). The United Kingdom used the long scale billion until 1974, when the government officially switched to the short scale, but since the 1950s the short scale had already been increasingly used in technical writing and journalism; the long scale definition still enjoys some limited usage in the UK.
