The order of operations (PEMDAS/BODMAS) states that expressions should be evaluated from left to right, with parentheses first, followed by exponents, then multiplication and division, and finally addition and subtraction. For example, the expression 3x^2 + 4x - 5 can be written as a polynomial. Here are some examples of polynomials: 1. \( x^2
