What does 5 evaluate to ?

A. +5

B. -11

C. +11

D. -5

Correct Answer : 

A). +5

 

Explanation : The expression “5” simply evaluates to the positive number 5. In mathematics, it represents a positive integer, so it is equivalent to +5.

 

Core Explanation:

  1. Numeric
    Literal:

    • 5 is
      an integer literal (base 10)
    • Python
      interprets it as the numeric value 5
    • Type: <class
      ‘int’> (verified with type(5))
  2. Comparison

  1. Key
    Characteristics of Integers in Python:

    • No
      decimal points (unlike floats)
    • Can
      be positive, negative, or zero ( 5, 0, +5)
    • Support
      mathematical operations:

python

print(5 * 2)    # 10
(int)

print(5 / 2)    # 2.5
(float   division converts to float)

print(5 // 2)   # 2
(int   floor division)


💻 Practical Verification:

Test in Python interpreter:

python

>>> 5

5              #
Output value

 

>>> type(5)

<class ‘int’>  #
Confirmed integer type

 

>>> 5 == 5.0  
# Value equality check

True           # Same
numeric value (but different types)

 

>>> 5 == “5”   # Compare int vs string

False          #
Different types and values


❌ Common MCQ Traps to Avoid:

  1. Confusing 5 with “5”:
    • 5 is
      a number → can do math
    • “5” is
      text → “5” + “2” = “52” (concatenation)
  2. Assuming
    automatic type conversion:

python

print(5 + int(“2”))  # 7 (explicit conversion works)

print(5 + “2”)       # TypeError (no implicit conversion)

  1. Misinterpreting
    division:

    • 5 /
      2 → 2.5 (float)
    • 5
      // 2 → 2 (int floor division)

✅ Sample MCQ Scenarios:

Q1: What is the output of print(type(5))?
a) <class ‘str’>
b) <class ‘float’>
c) <class ‘int’> 

Q2: Which evaluates to an integer?
a) “5”
b) 5.0
c) 5 
d) ‘5’

Q3: What does 5 + 3 * 2 evaluate to?
a) 16
b) 11  (Order: 3*2=6 → 5+6)
c) 13
d) SyntaxError


⚡ Pro Tip:

Use Python’s interactive mode (python in terminal) to
instantly test expressions during study. This builds intuition for how Python
evaluates literals and operations.

Key Takeaway:
5 is always an integer literal in Python. Understanding
this distinction between numbers (5), decimals (5.0), and strings (“5”)
is crucial for avoiding type errors and acing Python MCQs.
