The pattern is that the result of subtracting the two numbers is the first integer in the answer, followed by the result of adding the numbers. For example, 6 + 4 = 210. 6 - 4 = 2 and 6 + 4 = 10.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.
