Teach Your Kids Arithmetic - Fractions, Those Devils! by Joe Pagano
... And these monsters are quite friendly when we perform the arithmetic operations of multiplication or division (which will not be discussed here; you’ll just have to wait until I write that article). However, add or subtract—now we’re talking serious business. Students would cringe at the thought of adding two fractions with unusually different denominators, not to mention three fractions with different bottoms. I guess “bottoms up” would not apply here.

The GED Math Test: About the Casio fx-260 Calculator by Leonard Williams
... Using number keys 0-9, and basic operation keys for addition, multiplication, subtraction and division. Learning the location of the decimal point key, equals and percent, and how and when each is used. Using the 'Shift' key -- to change other keys to alternate functions. How the 'Change Sign' and 'Fraction' keys work, and when to use them. How the 'Square' and 'Square Root' keys work, and when to use them. The 'Parenthesis' keys are important, since these keys are used to control the order ...

Creating a Blackjack Card Counting Strategy by Norman Wattenberger
... division, multiplication, tables.) TC systems generally use this TC for all playing decisions. Most also use it for betting decisions. There are exceptions to both of these rules. RC strategies are generally easier to use and TC strategies are generally more accurate. Balanced vs. Unbalanced - In a balanced strategy, all of the point values sum to zero. In an unbalanced strategy, the sum of all the cards is positive. Unbalanced strategies have an advantage because they can be used in the ...

Flexible Estimation in Math by Peter Waycik
... For instance, ask them how long they think it will take to get to hockey practice (time), have them add up the cost of the groceries as you are shopping (money), get them to count the number of people in one area of the mall and have them estimate how many people are in the whole mall (multiplication or addition). Educators should make estimation a regular part of the problem solving process. In a science investigation, students make hypotheses and predictions, so why not make an estimate ...

History of the Computer - Computers and Technology by Michael Cooper
... They performed basic math functions such as multiplication and division and displayed the results in a variety of methods. Some computers displayed results in a binary representation of electronic lamps. Binary denotes using only ones and zeros thus, lit lamps represented ones and unlit lamps represented zeros. The irony of this is that people needed to perform another mathematical function to translate binary to decimal to make it readable to the user.
