    • How Do You Simplify Imaginary Numbers?

      Q: How Do You Simplify Imaginary Numbers?

      A: Imaginary numbers are typically simplified in the same way that expressions with the variable x are simplified, with the exception of the expression i^2, which has a value equal to -1. For example, the expression 2i + 8i can be simplified by writing it first as (2 + 8) * i, with the final expression written as 10i.

    • Why Are Points Connected in a Line Graph but Not in a Bar Graph?

      Q: Why Are Points Connected in a Line Graph but Not in a Bar Graph?

      A: A line graph is a graph that charts the relationship between two variables or a progression of a single quantity through time. Without the lines connecting points of data, it would be difficult to make sense of the data being presented if there was no overall trend between the dots. A bar graph, on the other hand, is meant to compare two or more statistics, such as population figures.
