DAY 342:

Today’s Challenge

. . . is a regular favourite of ours where at least one decimal number is present in trying to arrive at our signature target number, 7.

Using the numbers 0.25, 2, 4 and 6 once each, and with the four arithmetical operations – × ÷ available, can you arrive at 7 in two completely different ways?

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 3rd & 5th columns of the playing board contain the following fourteen numbers:

4    8    11    12    14    15    17    18    25    35    44    80    81    84

How many pairs of consecutive numbers are listed?

Make 342 Challenge

Can you arrive at 342 by inserting 2, 3, 4, 5 and 5 into the gaps below?
