original: associativity of addition : for any integers , a , b and c , -lrb- a + b -rrb- + c = a + -lrb- b + c -rrb- .
simplifications: when adding numbers , the sum of -lrb- a + b -rrb- + c is the same as a + -lrb- b + c -rrb- . associativity of addition : for any integers , a , b and c , -lrb- a + b -rrb- + c = a + -lrb- b + c -rrb- . associativity of addition : for any integers , a , b and c , -lrb- a + b -rrb- + c = a + -lrb- b + c -rrb- . associativity of addition : for any integers , a , b and c , -lrb- a + b -rrb- + c = a + -lrb- b + c -rrb- . associativity of addition : for any integers , a , b , and c , -lrb- a + b -rrb- + c = a + -lrb- b + c -rrb- . to add integers , -lrb- a + b -rrb- + c = a + -lrb- b + c -rrb- . associativity of addition : for any integers , a , b , and c ; -lrb- a + b -rrb- + c = a + -lrb- b + c -rrb- . associativity of addition : for any integers a , b and c , -lrb- a + b -rrb- + c = a + -lrb- b + c -rrb- .
