When playing Mathematically Possible, players must analyse which numbers can (or can’t) be made from the three numbers rolled on their dice, but this particular challenge is slightly different as you are only allowed to add and subtract (+ and –) when calculating.
Use the numbers 3, 6 and 10 once each to find the only four target numbers from 1-30 that are mathematically possible to achieve.
The 7puzzle Challenge
The playing board of the 7puzzle game is a 7-by-7 grid containing 49 different numbers, ranging from 2 up to 84.
The 1st & 3rd rows of the playing board contain the following fourteen numbers:
2 9 13 14 15 22 25 36 40 42 45 66 72 80
What is the sum of the multiples of 7 listed above?
