Question
If 34 – 28 means 952, 544 + 8 means 68, 20
÷ 5 means 25, 20 x 10 means 10, then 375 – 11 x 270 ÷ 550 + 11 x 35 = ?Solution
Given that: 34 – 28 = 952. But actually 34 x 28 = 952. So, – means x. Given that: 544 + 8 = 68. But actually 544 ÷ 8 = 68. So, + means ÷. Given that: 20 ÷ 5 = 25. But actually 20 + 5 = 25. So, ÷ means +. Given that: 20 x 10 = 10. But actually 20 – 10 = 10. So, x means –. Given expression =375 – 11 x 270 ÷ 550 + 11 x 35 =? 375 x 11 – 270 + 550 ÷ 11 – 35 4125 – 270 + 50 – 35 3870
