BODMAS নিয়মের সাহায্যে সমীকরণটি সমাধান করা হয়:
আসুন একে একে প্রতিটি বিকল্প যাচাই করা যাক।
বিকল্প 1) -, ÷, ×, =
⇒ 23 - 2 ÷ 2 × 5 = 18
⇒ 23 - 1 × 5 = 18
⇒ 23 - 5 = 18
⇒ 18 = 18
⇒ বামপক্ষ = ডানপক্ষ
বিকল্প 2) -, ÷, +, =
⇒ 23 - 2 ÷ 2 + 5 = 18
⇒ 23 - 1 + 5 = 18
⇒ 28 - 1 = 18
⇒ 27 ≠ 18
⇒ বামপক্ষ ≠ ডানপক্ষ
বিকল্প 3) -, ÷, =, +
⇒ 23 - 2 ÷ 2 = 5 + 18
⇒ 23 - 1 = 5 + 18
⇒ 22 ≠ 23
⇒বামপক্ষ ≠ ডানপক্ষ
বিকল্প 4) -, ×, ÷, =
⇒ 23 - 2 × 2 ÷ 5 = 18
⇒ 23 - 2 × 0.4 = 18
⇒ 23 - 0.8 = 18
⇒ 22.2 ≠ 18
⇒ বামপক্ষ ≠ ডানপক্ষ
সুতরাং, সঠিক উত্তর হল "বিকল্প 1"
