Compound interest. Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously-accumulated interest.
Guanches (also: Guanchis or Guanchetos) refer to the aboriginal Berber inhabitants of the Canary Islands. It is believed that they migrated to the archipelago around 1000 BC or perhaps earlier.
The lesser-known, smaller relative of the camel, the guanaco is an even-toed hoofed mammal. It has a similar build to the camel, with long, thin legs and broad feet with two toes on each foot. The guanaco lives in the dry, open plains and mountains of South America, where temperatures get cold enough for snow. It has special red blood cells that allow it to carry a lot of oxygen in its body, which means it can survive at great heights, where the air is thinner.
