Surface Forms
Morphology
The meaning 'the number 400' is directly and compositionally derived from combining 'four' (the digit 4) with 'hundred' (the multiplier 100), following standard English numeric formation. This numeric construction is regular, highly predictable and cross-linguistically common, so a B1 learner who knows both constituents will understand it.
Etymology
Four hundred is just the number made from four and hundred, meaning 'four times one hundred'. Imagine four stacks of one hundred coins to see the picture — that's why it equals '400'.
