DAY 351:

Today’s Challenge

. . . looks straightforward enough but the numbers are written in words, perhaps a bit trickier than you think!  Add these four numbers together and write your answer in words:

  •  Two hundred and four thousand and nine,
  •  Seventy thousand, nine hundred and eight,
  •  Four hundred and fifty thousand and seventy,
  •  One hundred and seven thousand, three hundred and ninety-five.

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 4th & 5th columns of the playing board contain the following fourteen numbers:

3    6    8    11    14    18    20    25    42    44    63    72    77    84

How many numbers listed are NOT multiples of 3, 5 or 7?

Make 351 Challenge

Can you arrive at 351 by inserting 1, 2, 3, 4 and 5 into the gaps on each line?

  •  (◯+◯)²×double◯–(◯×◯)² = 351
  •  (◯–◯)³×(◯×◯–◯) = 351
