use another operand within the boxes, It's as simple as, [15] + [11] + [{9-5}] = 30 PS: The answer lies within your knowledge of how brackets work. 41 Likes 2 Shares |

You should first forget about repeating numbers, you will never get an answer that way. There is no answer. You can never get an even number by adding three odd/ prime numbers. If you come up with an answer, i will hit my head against a wall. 12 Likes 3 Shares |

It's simple base addition let's use base 9: So 99+99+99=30 Those who have done computer science or electrical engineering will get it, for those who don't, we operate using base10, so for base9 let's all calculations such as 4+4=8 are the same as base10, but when it comes to calculations like 9+9= 20, it's just like base2 where 12+12=10. You see in base9 the number 9 is the last number, so there's no 10, so when you add the last numbers together you get 20 for arithmetic convenience, how? well in base9 there are 10 numbers: 0,1,2,3,4,5,6,7,8,9 so it'd expected that if you add the tenth number to itself it should give the twentieth number then if you add again it should give the thirtieth number. 12 Likes 1 Share |

Here's my attempt. N/B: The question didn't specify the units of the number(s) on the two sides of the equation, thus I'm free to assume mine. So, 1 + 1 + 5 = 30 How; 1 (day) + 1 (hour) + 5 (hours) = 30 (hours). That's the way I choose to reason this, and I'm entitled to my opinion. Thanks. ![]() 52 Likes 6 Shares |
