The numbers 1 up to and including 8 must be put in the circles of the picture. However, numbers in neighboring circles must differ by more than 1. For example, circles connected to a circle with a 4 may not contain a 3 or a 5.
You are provided with a grid (as shown in the picture). Can you fill the squares with numbers 1-8 in a manner that none of the two consecutive numbers are placed next to each other in any direction (vertically, horizontally or diagonally?)
Arrange the Numbers 0 1 2 3 4 5 6 7 8 9.
so that they sum up to 100.
You Can use only + and -
For example for 0 1 2 3 4 sum up to 11
Can you arrange the numbers from 1 to 9 on a tic tac toe board in a manner that the numbers in each row, column and diagonal adds up to 15. Remember that you have to use all the 9 numbers and thus you cannot repeat.
