Analogies 1

Analogies are usually comparisons of words and concepts, such as: light:day::dark:night (which reads - light is to day just as dark is to night). The objective in analogies is to figure out the relationship.
We will use analogies with math problems, and the objective will be the same. For example: 6:4::8:6 This would read 6 is to 4 just as 8 is to 6 and the relationship would be subtraction (-2).
