Correct Answer

Symbolic Substitution: Translate the alphabets into mathematical operators based on the given legend. The expression reconstructs to: 1 x 45 + 2 ÷ 2 - 4.BODMAS......

💡 Analysis & Explanation

Symbolic Substitution ▼

Translate the alphabets into mathematical operators based on the given legend. The expression reconstructs to: 1 x 45 + 2 ÷ 2 - 4.

BODMAS Initialization (Division) ▼

The first step prioritizes division. Calculate 2 ÷ 2 = 1.

BODMAS Secondary (Multiplication) ▼

Next, evaluate the multiplication block. Calculate 1 x 45 = 45.

Final Synthesis ▼

Combine all resolved values through addition and subtraction: 45 + 1 - 4 = 42.

Conclusion ▼

The mathematical simplification evaluates precisely to 42.
