दिलेले समीकरण: 40 - 220 ÷ 2 × 2 + 20 = 200.
आता, दोन चिन्हे आणि दोन संख्यांची अदलाबदल करणे,
1) 20 आणि 40, + आणि -
दिलेले समीकरण: 40 - 220 ÷ 2 × 2 + 20 = 200
20 आणि 40, + आणि -' अदलाबदल केल्यानंतर, आपल्याला मिळते:
डा.बा. = 20 + 220 ÷ 2 × 2 - 40
= 20 + 110 × 2 - 40
= 20 + 220 - 40
= 240 - 40
= 200 = उ.बा.
2) 2 आणि 20, + आणि ×
दिलेले समीकरण: 40 - 220 ÷ 2 × 2 + 20 = 200
'2 आणि 20, + आणि ×' अदलाबदल केल्यानंतर, आपल्याला मिळते:
डा.बा. = 40 - 220 ÷ 20 × 20 + 2
= 40 - 11 × 20 + 2
= 40 - 220 + 2
= 42 - 220
= -178 ≠ उ.बा.
3) 220 आणि 40,+ आणि ×
दिलेले समीकरण:40 - 220 ÷ 2 × 2 + 20 = 200
'220 आणि 40,+ आणि ×' अदलाबदल केल्यानंतर, आपल्याला मिळते:
डा.बा. = 220 - 40 ÷ 2 + 2 × 20
= 220 - 20 + 2 × 20
= 220 - 20 + 40
= 260 - 20
= 240 ≠ उ.बा..
4) 220 आणि 20, ÷ आणि ×
दिलेले समीकरण:40 - 220 ÷ 2 × 2 + 20 = 200
'220 आणि 20, ÷ आणि ×' अदलाबदल केल्यानंतर, आपल्याला मिळते:
डा.बा.= 40 - 20 × 2 ÷ 2 + 220
= 40 - 20 × 1 + 220
= 40 – 20 + 220
= 260 - 20
= 240 ≠ उ.बा..
