প্রশ্ন অনুসারে, * চিহ্নগুলি প্রতিস্থাপন করার পরে আমরা পাই:
তাই,
- বিকল্প - (1) : ÷, −, ×, +
66 ÷ 6 − 12 × 3 + 15 = 12
11 − 12 × 3 + 15 = 12
11 + 15 - 36 = 12
26 - 36 = 12
-10 ≠ 12 (বাঁদিক ≠ ডান দিক)
- বিকল্প - (2) : +, −, ÷, ×
66 + 6 − 12 ÷ 3 × 15 = 12
66 + 6 − 4 × 15 = 12
66 + 6 − 60 = 12
72 - 60 = 12
12 = 12 (বাঁদিক = ডান দিক)
- বিকল্প - (3) : ÷, ×, +, −
66 ÷ 6 × 12 + 3 − 15 = 12
11 × 12 + 3 − 15 = 12
132 + 3 - 15 = 12
135 - 15 = 12
115 ≠ 12 (বাঁদিক ≠ ডান দিক)
- বিকল্প - (4) : ×, −, ÷, +
66 × 6 − 12 ÷ 3 + 15 = 12
66 × 6 − 4 + 15 = 12
396 + 15 - 4 = 12
411 - 4 = 12
407 ≠ 12 (বাঁদিক ≠ ডান দিক)
