Strategies

This exercise can be done in several different ways, for example, thinking of numbers on a number line, or geometrically as a quantity.

  1. Positive numbers are always greater than negative numbers and negative numbers are always lesser than positive numbers.
  2. The sign of the number is irrelevant when considering the absolute value or magnitude.
  3. Although the answer for the first question and the second question are different most of the time, there are occasions where they are the same so it is important to read carefully.

Real-life Applications

  1. Absolute value is used for determining elevation for places above and below sea level.
  2. Negative numbers are used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature.
