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.
Quick Answer. Computers use binary numbers because they have circuits which are either on or off, which gives them two states to work from to make calculations and run processes. The two-digit, or base 2, number system is much easier for the computer to process with the circuits they have. The binary numbers have values for each space in a number, just like regular numbers with the ones, tens and hundreds places.
