The Main Challenge

If you allocate each letter of the English alphabet a numerical value as follows: A=1 B=2 C=3 . . . Z=26, the value of the word ‘CAT’ would be 24, simply calculated by doing 3+1+20.

Following this rule, what is the value of the word ‘PUZZLED‘?

  •   1   2   4
  •   1   4   5
  •   2   4   4
  •   3   3   3
  •   4   4   5

The Target Challenge

Can you arrive at 4 by inserting 1, 3, 5 and 7 into the gaps on each line?

  •  (+)(+) = 4
  •  (+)÷(×) = 4
  •  √(×–◯×◯) = 4
  •  (◯–◯)×(◯–◯) = 4
