the foundational patterns present on the first page‚ it is sure there must be a mathematical relationship of row number and numerator number in between. To search the deeper relationship‚ the plot diagram is the meaningful and practical choice due to the shared feature with function diagram. I decide to let numerator as the y-axis and nth row as the x-axis. Numerator Row number Fig.2-1 By looking through the diagram (Fig.2-1)‚ the shape of the curve seem to be similar with the quadratic

Fraction – is defined as a part of a whole. In some other books‚ it is defined as a number written in the form ab ‚ where “a” and “b” are numbers and “b” is not equal to zero. Basic Parts of a Fraction * Numerator – the number above tells how many parts are taken. * Denominator – the number below tells how many equal parts the whole is divided. * Fraction bar – line that separates the two numbers. It also indicates division. There are several kinds of fraction and they are grouped

Law Benford’s law‚ aka first-digit law‚ states that in lists of numbers of naturally occurring data‚ the leading digit is distributed in a specific‚ non-uniform way. In number sequences‚ most people assume that in a string of numbers sampled randomly all nine numbers would be equally probable for the leading digit. Benford’s Law states otherwise. He found that the number 1 will appear first about 30% of the time and the number 9 will only appear first around 4.5%. Naturally occurring can be anything

sixth row‚ the pattern for the numerator for the first five rows is observed. Since the numerator is the same in each row (not counting the first and the last number in each row)‚ I can observe the numerator in the middle of each row. The numerators from row 1 to row 5 are 1‚3‚6‚10‚15 Table 1: A table showing the relationship between the row number and the numerator. The table also shows the relationship between the numerators in each row. Row | Numerator | 1st differences | 2nd differences | 1

called decimal systems. Decimal numbers are normally numbered from 0-10. Decimal numbering is sometimes referred to as base 10. The second numbering system that computers use is binary systems. Unlike the decimal system‚ there are only two numbers used in binary systems. One of these numbers is zero that represents false and off in computer‚ math‚ and measurement. The other number in the binary system is one that represents true and on for computer math. Binary numbers are sometimes referred to as
