    Use each of the whole numbers 2 to 13 once, writing one in each box, so that the four calculations are correct.

    \(\square + \square + \square = 36\)

    \(\square + \square + \square = 26\)

    \(\square + \square + \square = 10\)

    \(\square + \square + \square = 18\)

    Show answer
    \(11 + 12 + 13 = 36\); \(7 + 9 + 10 = 26\); \(2 + 3 + 5 = 10\); \(4 + 6 + 8 = 18\) (the three numbers in each calculation may be in any order)
