In addition, if the places of the added numbers change, the sum does not change. for a N and b N; A + b = b + a is the variable property of addition.

3. Merging feature:

In finding the sum of the three natural numbers, the sum of the two desired terms can be summed up by the third. The merger property, a + (b + c) = (a + b) + c If there is a positive number k that satisfies the equation a = b + k; It is said that a is greater than b. Shown as a> b. If a and b are any two positive numbers, a = b, ab. A second decimal system operation can be described by successive addition. 5 + 5 + 5 for a N, b N and c N; (a + b) + c = a + (b + c).
