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.
At their fundamental level, computers use a numeral system whose digits consist of only two possible values. These digits can either be zeros or ones. This system is known as Binary. It may seem limiting at first, but any number can be represented in Binary. In most cases, you simply need more zeros and ones.
