Place the numbers 1 to 9 in the circles, such that each side of the triangle adds up to 17
In clock wise from top 3, 7, 5, 2, 6, 8, 1, 4, 9
Draw a triangle. Write one of the numbers from 1 to 6 at each corner and one of the numbers along each side (no repeats). Can you arrange them so each side adds up to the same number?
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.
Using all the numbers from 1 to 10, put them into pairs, so that one pair adds to 6, another pair to 7, a third pair to 9, a fourth pair to 16 and the final pair add to 17.
Put numbers 7, 8 and 9 at the corners of a triangle. Now place 1, 2, 3, 4, 5, 6 in twos on each side to make the same total on all three sides (include the numbers at the corners)?
Place numbers 1 to 15 in the white circles so that the distance from 1 to 2, 2-3, 3-4 and so on progressively increase each time.
