In math, number and word notation is simply writing the significant digits of a large number and using words for the place value. For example, the number 45,000 in number and word notation is 45 thousand.
Often used in media publications, such as newspaper or magazine articles, number and word notation makes for easier reading and comprehension of large numbers. It is much more concise to write the words "two billion" or "2 billion" instead of 2,000,000,000.
Standard notation is initially taught when children first learn how to write numbers. That is numbers only, such as 1,000 or 7,600,000. When teaching students how to write in number and word notation, the first step is to note the significant numbers. Follow those numbers by the words notating their place value. If there are two significant numbers separated by a comma, as in 7,600,000, there is an extra step. Replace the comma with a period, and use the place value of the first number. Therefore, the correct number and word notation for that standard number is 7.6 million. Since it can be challenging for some to learn, a good trick is to circle the significant numbers, then determine their place value. To ensure accuracy, simply go back and double-check the number in its standard notation.

Full Answer >Mathematical equations called functions use input and output replace the variables in an equation. The input is the known variable, while the output is the solution. Use functions any time a variable (x) transforms in a relationship to equal a new variable (y).
Full Answer >The equivalent of 401 in Roman numerals is CDI. The Roman numeral system uses letters rather than numerals. The basic letters and their numeric equivalents are as follows: I equals one, V equals five, X equals 10, L equals 50, C equals 100, D equals 500 and M equals 1,000.
Full Answer >One billion in numerals is written as 1,000,000,000. To write one billion in numerals, you will need ten figures before the decimal point. For example, seven billion translates to 7,000,000,000.
