... Human thinks: ok, how about ninety-five? Human types in two digits: ‘9’ and ‘5’ Here the typing-order is important: because “95” means 9-times-10, plus 5 • Computer sees two ASCII values: 57, then 53 • It must convert 57 into 9, and 53 into 5, and then do a multiplication (by 10) and an addition ste ...

... **Square Root: Think: “What times itself is that number” (ex: √25 = 5 because 5 x 5 = 25) **When you have a square root number, and it is NOT a perfect square, think “what times what is that number” and write it under the √. THEN, see if one of those numbers is a perfect square! EXAMPLE: √12 Step 1: ...

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.
