Question
If, 40 – 14 means 560, 168 + 8 means
21, 26 ÷ 2 means 28, 8 x 7 means 1, then 410 – 7 x 290 ÷ 350 + 7 x 21 = ?Solution
Given that: 40 – 14 = 560. But actually 40 x 14 = 560. So, – means x. Given that: 168 + 8 = 21. But actually 168 ÷ 8 = 21. So, + means ÷. Given that: 26 ÷ 2 = 28. But actually 26 + 2 = 28. So, ÷ means +. Given that: 8 x 7 = 1. But actually 8 – 7 = 1. So, x means –. Given expression =410 – 7 x 290 ÷ 350 + 7 x 21 =? 410 x 7 – 290 + 350 ÷ 7 – 21 =? 2870 – 290 + 50 – 21 2609
