Main article: Different calculators follow different orders of operations. Many simple calculators without a stack implement working left to right without any priority given to different operators, for example typing 1 + 2 × 3 yields 9, while more sophisticated calculators will use a more standard priority, for example typing 1 + 2 × 3 yields 7. The program uses the former in its standard view and the latter in its scientific and programmer views. Chain input expects two operands and an operator. When the next operator is pressed, the expression is immediately evaluated and the answer becomes the left hand of the next operator. Advanced calculators allow entry of the whole expression, grouped as necessary, and evaluates only when the user uses the equals sign. Calculators may associate exponents to the left or to the right depending on the model or the evaluation mode.

For example, the expression a^ b^ c is interpreted as a ( b c) on the and the in 'Mathprint mode', whereas it is interpreted as ( a b) c on the and the in 'Classic mode'. An expression like 1/2 x is interpreted as 1/(2 x) by, but as (1/2) x by and every other TI calculator released since 1996, as well as by all calculators with algebraic notation. While the first interpretation may be expected by some users, only the latter is in agreement with the standard rule that multiplication and division are of equal precedence, so 1/2 x is read one divided by two and the answer multiplied by x. When the user is unsure how a calculator will interpret an expression, it is a good idea to use parentheses so there is no ambiguity.

Calculators that utilize (RPN), also known as postfix notation, use a to enter formulas without the need for parentheses. Programming languages [ ] Some use precedence levels that conform to the order commonly used in mathematics, though others, such as, or, have no precedence rules (in APL, evaluation is strictly right to left; in Smalltalk and Occam, it is strictly left to right). In addition, because many operators are not associative, the order within any single level is usually defined by grouping left to right so that 16/4/4 is interpreted as (16/4)/4 = 1 rather than 16/(4/4) = 16; such operators are perhaps misleadingly referred to as 'left associative'.

Computer Algebra is the discipline that studies the algorithms for Symbolic Computation. Computation, one computes with symbols, rather than with numbers. In this course we are mostly. Lectures and classes are Tuesday 09.15 (3W 3.7), Wednesday 09.15 (1WN 3.23) and Friday 10:15 (1E 3.9, computer lab., in weeks 1-3, then 8W2.28). There are two user interfaces to Maple: `classic worksheet' and `standard'. 'Computer Algebra and Symbolic Computation: Elementary Algorithms' by Joel S.
