Binary Numbers
... In order to understand the binary numbering system lets first look at our decimal system. • The decimal numbering system consists of the numbers 0 through 9. • After nine we place a 1 in the tens column and start again with 0. Which gives us 10. • The decimal system is also known as base 10 because ...

... RATIOS AND RATES Quantities such as 8 feet, 16 cents or 10 hours are numerical quantities written with units. A ratio is a comparison of two quantities with the same units. For example, if we want to compare the heights of two trees, one 6 feet tall and the other 8 feet tall, we can write this ratio ...

A pocket watch is placed next to a digital clock. Several times a day
... Several times a day, the number of minutes shown by the digital clock is equal to the number of degrees between the hands of the watch. (The watch does not have a second hand.) As you can see, 10:27 is not one of those times — the angle between the hands is much greater than 27°. If fractional ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
