means The set of circumstances, consequences, or wreckage that follows a significant or destructive event.

from A literal farming word in disguise. 'After' is plain old 'after,' but 'math' here has nothing to do with numbers — it comes from Old English 'mæð,' meaning a mowing or a crop of grass cut down. The 'aftermath' was the second growth of grass that sprang up after the first harvest — what some farmers also called the 'rowen.' Over time the word drifted from the field to the figurative, so that the thing growing back after the scythe became the situation lingering after any kind of blow.
