DAY 224:

Today’s Challenge

Three UNIQUE digits must be used to arrive at the target number 37.

The rule – players must multiply two numbers together, then either add or subtract the third number to achieve the target answer of 37.

Using the formula (a×b)±c, where a, b and c are three unique digits from 1-9, one way of achieving 37 is (7×5)+2, can you find the other SEVEN ways?

[Note:  (7×5)+2 = 37 and  (5×7)+2 = 37 counts as just ONE way.]

The 7puzzle Challenge

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

The 5th & 6th rows of the playing board contain the following fourteen numbers:

5    6    7    12    16    18    20    21    33    49    50    56    81    84

From the list, which three different numbers have a sum of 100?

Make 224 Challenge

Can you arrive at 224 by inserting 1, 2, 3 and 4 into the gaps on each line?

  •  (5+◯)×◯×(◯²–◯) = 224
  •  (◯³÷◯)×(2×◯+◯) = 224
