Refactored and Enhanced Test Cases for the Calculate function

Test Case: Basic Arithmetic (Simple Additions)

Given:

1 + 1 =
2.5 + 2.5 =

Expect:

1 + 1 = 2
2.5 + 2.5 = 5

Test Case: Variable Assignment with Various Valid Symbols

Given:

a = 5
_var = 6
alpha123 = 7

Expect:

a = 5
_var = 6
alpha123 = 7

Test Case: Arithmetic Using Variables (Including Subtraction)

Given:

a = 6
a - 2 =

Expect:

a = 6
a - 2 = 4

Test Case: Undefined Variable Referenced with Arithmetic

Given:

a = 1
a + unknown_var =

Expect:

a = 1
a + unknown_var = Error: Undefined symbol unknown_var

Test Case: Complex Arithmetic with Nested Expressions

Given:

2 * (3 + (4 - 1)) =

Expect:

2 * (3 + (4 - 1)) = 12

Test Case: Factorials and Advanced Operators
