Number recognition - Elementary Math

Jeremy lives in a neighborhood where the houses are built at different years. The list below shows the names of four of his neighbors and the years their house was built. According to the list, which of the houses was built first?

The Andersons own a house that was built in 1981
The Craigs own a house that was built in 1978
The Drakes own a house that was built in 1985
The Edwards own a house that was built in 1973

Answer : 1973

Explanation:

The problem is asking for the house that was built first meaning to find the earliest year among the four different years that are presented. The way to do this is to write down the years from smallest to largest and compare them. The number that is the smallest will represent the house that was built first. Lets try this as follows:
1973, 1978, 1981, 1985
From the above list we realize that the smallest number is 1973. Therefore the house belonging to the Edwards was built first.
