Math teachers love me because I stand for nothing at all, but on a digital midnight clock, four of me show that a brand-new day has started. What am I?
Zero
The riddle contrasts the mathematical value of zero (representing an empty quantity) with 24-hour digital clock displays. At midnight, military and international digital clocks reset to 00:00, using four zeroes to signify the precise start of the new day.
