triangle of numbers
Insert the numbers from 1 to 15 in the boxes below so that the subtraction of two numbers beside each other (their absolute value) results their above value. For example:
| K – L | = G | G-H | =D
| L-M | = H | H-I | =E
And so on.
The numbers can't be repeated and should not be zero.
