EQUATION: 4 + 18 – 3 × 2 ÷ 6 = 101. Interchanging ÷ and –= 4 + 18 ÷ 3 × 2 - 6 = 4 + 6 × 2 - 6 = 4 + 12 - 6= 16 - 610 = 102.Interchanging × and += 4 × 18 – 3 + 2 ÷ 6 = 4 × 18 – 3 + 0.3333= 72 - 3 + 0.333= 72.333 - 3 69. 33 ≠ 103.Interchanging × and ÷= 4 + 18 – 3 ÷ 2 × 6 = 4 + 18 – 1.5 × 6 = 4 + 18 – 9= 22 - 9 13 ≠ 104.Interchanging + and –= 4 - 18 + 3 × 2 ÷ 6 = 4 - 18 + 3 × 0.3333= 4 - 18 + 1= 4 - 17- 13 ≠ 10Hence, by interchanging "÷ and –" we get the correct ANSWER.
