When the Simplex LP or GRG Nonlinear **Solving** methods are used, Solver uses a Branch & Bound method for the **integer** constraints. This type of notation is referred to as infix since the operator is the two operands that it is working on. The operators and * still appear between the operands, but there is a *problem*. Does the work on A and B or does the * take B and C? In fact, you have been reading and writing these types of expressions for a long time and they do not cause you any *problem*. PEMDAS stands for: parentheses, exponents, multiplication, division, addition, subtraction Step 1: evaluate PARENTHESES PEMDAS order of evaluation: PARENTHESES, exponents, multiplication, division, addition, subtraction No parentheses to evaluate.

## Integer problem solving

Subtraction of *Integers* When subtracting *integers*, the additive inverse must be used. -6 - ( 8) = -6 (-8) = -14 Why has the subtraction *problem* become an addition *problem*? The Gaussian *integers*, with ordinary addition and multiplication of complex numbers, form an integral domain, usually written as are also known as Gaussian primes.

Such

problemsmay require computing time than the sameproblemwithout theintegerconstraints.

Step 3: MULTIPLICATION PEMDAS order of evaluation: parentheses, exponents, MULTIPLICATION, division, addition, subtraction There are operations that require multiplication. When a Solver model includes *integer*, or alldifferent constraints, it is ed an *integer* programming *problem*.

*Integer* constraints make a model non-convex, and finding the optimal solution to an *integer* programming *problem* is equivalent to *solving* a global optimization *problem*.
