The 7puzzle Challenge
The playing board of the 7puzzle game is a 7-by-7 grid of 49 different numbers, ranging from 2 up to 84.
The 2nd & 6th rows contain the following fourteen numbers:
5 8 12 17 18 20 28 33 48 49 55 56 63 64
What is the sum of the cube numbers?
Make 43 Challenge
Can you arrive at 43 by inserting 4, 5, 8 and 9 into the gaps on each line?
- ◯×◯–◯÷◯ = 43
- ◯²+◯×(◯–◯) = 43
- (◯+◯)×◯–◯² = 43
- (◯×√◯×√◯)–◯ = 43
- (◯–√◯)×◯+◯ = 43
