Subsection 2.1.1

Given the following code snippet, evaluate the final statement (the last line). If invalid, give the reason. If valid, what value is assigned to the variable?
🔗
beta = 1
omega = 2.5
alpha = 42
theta = 4
🔗

Subsection 2.1.2 SG1: Decide order of operations

There are no operators, so the only order is the order of the individual lines.

Subsection 2.1.3 SG2: Determine operator behavior based on operands

NOT USED IN THIS EXAMPLE.
🔗
🔗

Subsection 2.1.4 SG3: Solve arithmetic, expression, or operation

The value 1 is stored in beta, the value 2.5 is stored in omega, the value 42 is stored in alpha, and the value 4 is stored in the variable theta.
