Division is the most mentally difficult of the four basic operations of arithmetic, but the discipline and mastery of it provides an educational bridge from arithmetic to number theory and algebra. Teaching the objective concept of dividing integers introduces students to the arithmetic of fractions.
Although different species vary slightly, the base coat is generally a golden hue, the stripes ranging from dark brown or grey to black, and the underside of the tiger white. Interestingly, the skin of the tiger is also striped beneath the patterned fur. The darkness of the pigmentation of the skin seems to be directly related to the darkness of the fur. Tigers fur texture. Every tiger, as an individual animal, has a unique pattern of stripes. Therefore, scientists that are studying a particular animal may use these to identify their subject(s). This colouring and striped design is ideal for the camouflage needs of the animal.
Spotting is particularly obvious on Corbett's tiger (also called the Indochinese tiger. Shown below). The same applies to white tigers. Their striping can vary in colour from a ghost stripe (only obvious under the right angle of light reflection), to various greys, through to dark chocolate brown. Tiger stripes are like human fingerprints and no two tigers are ever marked the same.
