Digital root number is the number mod 11 (Ɛ), for example, 1972 is 1 + 9 + 7 + 2 = 19 = 17 which is 1 + 7 = 8, while in decimal the root of the same number (3110) is 5; and in base 16 a digital root of a number is the number mod 15 (0xF), for example, 0x7DF is 7 + 13 + 15 = 35 = 0x23 which is 2 + 3 = 5, while in decimal the root of the same number (2015) is 8. Digital roots form an important mechanic in the visual novel adventure
Ontario Highway 401 runs parallel to the former Highway 2 along the shore of the Saint Lawrence River within the Saint Lawrence Valley. Northeast of Brockville is the interchange with Highway 416, which heads north to Ottawa. At the Ontario–Quebec border, Highway 401 becomes Autoroute 20 and continues to Montreal. The MTO publishes yearly traffic volume data for provincial highways, expressed as an average daily vehicle count over the span of a year (AADT). The table below compares the AADT at several locations along Highway 401 using data from 1969, 1988, 2008 and 2016. Highway 401's history predates its designation by over two
