Final answer:
Brandon has demonstrated an understanding of subtraction by correctly stating that removing one cube from a set of thirteen cubes leaves twelve cubes. This showcases his ability to reduce the quantity of a set by a specific count and also indicates a basic knowledge of number manipulation.
Step-by-step explanation:
When Ms. Carter shows Brandon a set of cubes and he removes one, correctly stating that there are twelve cubes left, Brandon has demonstrated an understanding of the mathematical skill of subtraction. This is because Brandon has taken the total number of cubes, which was initially 13, and subtracted one cube to arrive at the new total. This method shows a grasp of the basic principle of subtraction, where you decrease the quantity of a set by removing elements. It is important to pay attention to the change in the number of items when performing subtraction with whole numbers, as well as to check the accuracy of the result through simple tests or logical reasoning.
In mathematics, understanding the relationship between numbers and how to manipulate them is critical. This is evident whether engaging in subtraction, as illustrated by Brandon's example, or through multiplication and other operations. Skills like these are essential not only to perform tasks but also to develop an intuitive sense for numbers and their behavior in various scenarios.
