This math riddle relates to Roman Numerals where 19 is IXX, 1 is I, and 20 is XX. By removing I from IXX, you are left with XX.
20 - 19 equals 1. This is a simple subtraction operation where you take 19 away from 20, leaving you with a result of 1.
You can't. 19 - 1 = 18, not 20.
Subtract a negative 1. 19 - (-1) = 20
20 - 19 = 1

Negative 19 minus 1 equals negative 20
You can't. 19 - 1 = 18, not 20.
This is a classic riddle that plays on the way numbers are written. If you take away the letter "N" from "NINETEEN," you are left with "INETEEN," which sounds like "TWENTY" when pronounced. So, by removing the "N" from "19," you are left with "20" phonetically.
