=== Associativity === [[File:AdditionAsc.svg|upright=0.5|thumb|2 + (1 + 3) = (2 + 1) + 3 with segmented rods]] Addition is [[associativity|associative]], which means that when three or more numbers are added together, the [[order of operations]] does not change the result. For any three numbers <math> a </math>, <math> b </math>, and <math> c </math>, it is true that:{{sfnp|Musser|Peterson|Burger|2013|p=[https://books.google.com/books?id=8jh7DwAAQBAJ&pg=PA90 90]}} <math display="block"> (a + b) + c = a + (b + c). </math> For example, <math> (1 + 2) + 3 = 1 + (2 + 3) </math>. When addition is used together with other operations, the [[order of operations]] becomes important. In the standard order of operations, addition is a lower priority than [[exponentiation]], [[nth root]]s, multiplication and division, but is given equal priority to subtraction.{{sfnp|Bronstein|Semendjajew|1987}} {{-}}
