Likewise, the second largest black square has area 1 / 16 , and the third largest black square has area 1 / 64 . The area taken up by all of the black squares together is therefore 1 / 4 + 1 / 16 + 1 / 64 + ⋯ , and this is also the area taken up by the gray squares and the white squares.
Word problem from the Līlāvatī (12th century), with its English translation and solution. In science education, a word problem is a mathematical exercise (such as in a textbook, worksheet, or exam) where significant background information on the problem is presented in ordinary language rather than in mathematical notation.
A simple fraction (also known as a common fraction or vulgar fraction) [n 1] is a rational number written as a/b or , where a and b are both integers. [9] As with other fractions, the denominator (b) cannot be zero. Examples include 1 / 2 , − 8 / 5 , −8 / 5 , and 8 / −5 .
As a collection, Problems and Other Stories is marked by the author’s growth as a writer, but the best stories in the book are best because they are about the subject which is most crucial to Updike. In those, form and feeling are one; the problem raised and the problem solved matter because the human heart is at stake; the drama is literally ...
If the discriminant is zero the fraction converges to the single root of multiplicity two. If the discriminant is positive the equation has two real roots, and the continued fraction converges to the larger (in absolute value) of these. The rate of convergence depends on the absolute value of the ratio between the two roots: the farther that ...
Continued fractions can also be applied to problems in number theory, and are especially useful in the study of Diophantine equations. In the late eighteenth century Lagrange used continued fractions to construct the general solution of Pell's equation, thus answering a question that had fascinated mathematicians for more than a thousand years.

Problem 3. The narrator A has four children, two of whom are attending college, and two in private school. Tuition for both college and preparatory school is $11, 000 annually. Forty-three percent of A's total income is collected in taxes, and 33% is alimony paid to ex-wife, C. A’s psychiatrist sessions cost $45, and the cost is $1.10 to do ...
"There was evidently no time to be lost, so, hastily adopting the Fourth Dimension of Space as a means of escape, he vanished through the wainscoting, and the house became quite quiet." [10] H.G. Wells famously employed the concept of a higher temporal dimension in his 1895 book The Time Machine.
