approximate equality Approximate equality is a concept used primarily in physics and engineering, and also occasionally in mathematics. Two quantities are approximately equal when they are close enough in value so the difference is inconsequential in practical terms. Approximate equality is symbolized by a squiggly equal sign ( ). As an example of how approximate equality can be used in mathematics, consider the positive square root of 2 (or 2 1/2 ). This is an irrational number ; when written in decimal form, it is nonterminating and nonrepeating.

Summary The smallest natural number is 1 and there is no largest natural number. Digits. Numbers are formed using the ten symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. These symbols are called digits or figures. To find the place value of a digit in a number, multiply the digit with the value of the place it occupies.Comparison of numbers. If two numbers have an unequal number of digits, then the number with the greater number of digits is greater.umbers are formed using the ten symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

What is the Chinese fraction approximation of pi? Since pi is a transcendental number, which is a kind of irrational number, there is no fractional form of pi. 22/7 is merely a fractional approximation. 22/7 (twenty two-sevenths).

CurvatureAnalysis The best approximating circle may lie either to the left of the curve, or to the right of the curve. If we care about this, then we establish a convention, such as giving the curvature positive sign if the circle lies to the left and negative sign if the circle lies to the right of the curve.

Color difference The International Commission on Illumination (CIE) calls their distance metric δE*ab (also called δE* , dE* , dE, or Delta E) where delta is a Greek letter often used to denote difference, and E stands for Empfindung; German for sensation.n the CIE 1931 color space, for example, the tolerance contours are defined by the MacAdam ellipse, which holds L* (lightness) fixed. As can be observed on the diagram on the right, the ellipses denoting the tolerance contours vary in size.
