“No calculator”

✅ Let’s solve it step-by-step using proper math rules:

We follow PEMDAS/BODMAS:

  • P/B: Parentheses/Brackets

  • E/O: Exponents/Orders

  • MD: Multiplication & Division (left to right)

  • AS: Addition & Subtraction (left to right)

There are no parentheses or exponents, so we do multiplication and division first, from left to right:

Step 1:
7 × 3 = 21
→ Now the expression becomes:
21 + 9 ÷ 3

Step 2:
9 ÷ 3 = 3
→ Now the expression becomes:
21 + 3

Step 3:
21 + 3 = 24


✅ Final Answer: 24
