প্রশ্ন অনুসারে, * চিহ্নগুলি প্রতিস্থাপন করার পরে:
অতএব,
- বিকল্প - (1) : +, ×, ÷, =
12 + 24 × 4 ÷ 2 = 60
12 + 24 × 2 = 60
12 + 48 = 60
60 = 60 (বাঁদিক = ডানদিক)
- বিকল্প - (2) : −, ×, +, =
12 - 24 × 4 + 2 = 60
12 + 2 - 96 = 60
14 - 96 = 60
82 ≠ 60 (বাঁদিক ≠ ডানদিক)
- বিকল্প - (3) : +, ×, −, =
12 + 24 × 4 - 2 = 60
12 + 96 - 2 = 60
108 - 2 = 60
106 ≠ 60 (বাঁদিক ≠ ডানদিক)
- বিকল্প - (4) : +, ÷, ×, =
12 + 24 ÷ 4 × 2 = 60
12 + 6 × 2 = 60
12 + 12 = 60
24 ≠ 60 (বাঁদিক ≠ ডানদিক)
