List of Measurable Verbs Used to Assess Learning Outcomes. Bloom's Taxonomy of Educational Objectives (1956): Cognitive Skills. A group of educators, led by Benjamin Bloom, identified a hierarchy of six categories of cognitive skills: knowledge, comprehension, application, analysis, synthesis and evaluation.
In normal maths, we don't use binary. We were taught to use our normal number system. Binary is much easier to do math in than normal numbers because you only are using two symbols - 1 and 0 instead of ten symbols - 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Computers use binary because they can only read and store an on or off charge. So, using 0 as off and 1 as on, we can use numbers in electrical wiring.
Trees are useful for arranging data in a hierarchy. As we will discuss later in this article, the time to search for an item can be drastically reduced by intelligently arranging the hierarchy. Before we can arrive at that topic, though, we need to first discuss a special kind of tree, the binary tree.
