1. Addition

   Addition is a mathematical operation that represents the total amount of objects together in a collection. It is signified by the plus sign. For example, in the picture on the right, there are 3 + 2 apples—meaning three apples and two apples together, which is a total of 5 apples. Therefore, 3 + 2 = 5. Besides counting fruits, addition can also represent combining other physical and abstract quantities using different kinds of objects: negative numbers, fractions, irrational numbers, vectors, decimals, functions, matrices and more. Addition follows several important patterns. It is commutative, meaning that order does not matter, and it is associative, meaning that when one adds more than two numbers, order in which addition is performed does not matter. Repeated addition of 1 is the same as counting; addition of 0 does not change a number. Addition also obeys predictable rules concerning related operations such as subtraction and multiplication. All of these rules can be proven, starting with the addition of natural numbers and generalizing up through the real numbers and beyond. General binary operations that continue these patterns are studied in abstract algebra.

   Right now natural parks have two big problems, the first one of them is to detect rhinos and non-authorized people in the area. That has been done with helicopters and planes up until now, but that is very expensive. In addition, you cannot see people who hide under trees from a plane. We solve this with thermal cameras. We use a drone that carries that kind of camera and looks over that area or those places suspected of having this kind of problem and it detects hot points. Like we see here. This shows people. Every pixel has a different color depending on how hot it is. This is placed on the drone, that takes a picture and reports directly to the ranger.
