Today’s Challenge

Using each of the numbers 0.1, 0.5, 3 and 6 once each, and with the four arithmetical operations available, can you arrive at the target answer of 7 by two different ways?

The 7puzzle Challenge

The playing board of the 7puzzle game is a 7-by-7 grid of 49 different numbers, ranging from up to 84.

2   6   7   9   14   15   16   21   22   40   50   72   81   84

Which three different numbers have a sum that is also on the list?

Make 51 Challenge

Can you arrive at 51 by inserting 4, 5, 6 and 7 into the gaps on each line?

  •  (+)×◯+◯ = 51
  •  ◯²+(◯+◯)÷ = 51
  •  ◯×◯++◯ = 51
  •  ◯×(◯+√◯)– = 51
