Question
If 30 – 22 means 660, 220 + 11 means 20, 14 ÷ 7 means
21, 15 x 12 means 3, then ' 333 – 8 x 255 ÷ 490 + 7 x 32 ' = ?Solution
Given that: 30 – 22 = 660. But actually 30 x 22 = 660. So, – means x. Given that: 220 + 11 = 20. But actually 220 ÷ 11 = 20. So, + means ÷. Given that: 14 ÷ 7 = 21. But actually 14 + 7 = 21. So, ÷ means +. Given that: 15 x 12 = 3. But actually 15 – 12 = 3. So, x means –. Given expression = 333 – 8 x 255 ÷ 490 + 7 x 32 =? 333 x 8 – 255 + 490 ÷ 7 – 32 2664 – 255 + 70 – 32 2447
