The GED Math Test: About the Casio fx-260 Calculator by Leonard Williams
... The 'Parenthesis' keys are important, since these keys are used to control the order of mathematical operations. Understanding the keys to raise numbers to another power, and for exponentials -- 'EXP' key -- used in scientific notation. Does it look complicated? Sure, and the Casio calculator used for the GED test has additional functions that can be used for highly complex mathematical functions. But don't worry. While it seems like a lot to learn -- and to understand -- the test requires ...
Using a Scientific Calculator In Mathematics Exams by N Pinhey
... Scientific calculators all use the same order for carrying out mathematical operations. This order is not necessarily the same as just reading a calculation from left to right. The rules for carrying out mathematical calculations specify the priority and so the order in which a calculation should be done - scientific calculators follow the same order. This order is sometimes abbreviated by terms such as BODMAS and BIDMAS to help students remember the order of doing calculations.
Teach Your Kids Arithmetic - The Quick-Add - Part I by Joe Pagano
... The consequences are truly disastrous as many students I have worked with realize—after I healed them of their mathematical ills—that they were actually good at math. Imagine what better problem solvers we would be in general if we had math on our side rather than against us! Let’s return to the idea of complements. In the 8 + 9 example, we see the sum is 17. How much faster would a child come up with the answer 17, if I said “What is 10 + 7?” Now the careful analysis of the difference ...
The Truth About Doublers by David Congreave
... If you involve yourself with a Doubler program with full knowledge of how they work, you are giving your approval to a fraudulent operation that is tantamount to theft. Would you steal your neighbours television set because they accidentally left their front door unlocked? Would you knowingly purchase stolen goods? If your answer is ‘Yes’ then this article probably means nothing to you. If the answer is ‘No’ then ask yourself why you would give your approval to a Doubler program?
The Hazard of Using Calculators at School by Victor Guskov
... Calculators of different kinds use different orders for carrying out mathematical operations, pressing keys, and their manuals have a bad habit to get lost. It is very easy to make simple mistakes when using one. You must think of the rough size of answers, so that you can see if an answer is sensible or not. To avoid mistakes you must repeat all calculations. If you get two different answers, then you must repeat all calculations for the third time.
History of the Computer - Computers and Technology by Michael Cooper
... The built-in operations were supposed to include everything that a modern general - purpose computer would need, even the all important Conditional Control Transfer Capability that would allow commands to be executed in any order, not just the order in which they were programmed. As people can see, it took quite a large amount of intelligence and fortitude to come to the 1990's style and use of computers. People have assumed that computers are a natural development in society and take them ...
Mathematics - We’re Counting on Help from Parents by Barbara Snyder
... The bottom line is that teachers don’t want students to take that shortcut until they have an understanding of how to do the mathematical operation (the long way) without the calculator. 5) Consider the two subjects in which student most often have homework - reading and mathematics. Think about the reasons for and benefits from homework assignments: practices prior learning; helps develop mastery; builds self discipline; encourages time management; teaches independent work; and teaches ...
Teach Your Kids Arithmetic - The Teenage Number Trick by Joe Pagano
... Thus understanding numbers and how to work with them via arithmetical operations form the foundations for all of mathematics. In this article, I want to give you a tool that you can pass to your children. This tool will give them the ability to multiply what I call any two “teenage numbers.” Teenage numbers are simply the numbers from 13-19—teenagers. (The method also works if we include 11 and 12, but for these poor souls the name of the method doesn’t apply as they are “pre-teens.” The ...
