Section 2.6 Evaluate Expressions-WE2-P2

Subgoals for evaluating an assignment statement.

Decide order of operations
1. Decompose as necessary
Determine operator behavior based on operands
1. Operator and operands must be compatible
Solve arithmetic, expression, or operation
1. Decompose as necessary

Subsection 2.6.1

For the assignment statements below, either give the new value of the assigned variable, or enter “invalid” if the statement would result in an error. Each problem is independent of the others (e.g. Question 2 does not depend on Question 1, only the “Given” code).

Subsection 2.6.2 Evaluate Expressions-WE2-P2

Given

alpha = 2
beta = 1
delta = '3.0'
theta = -1.3
