In the ten problems listed below, your task is to make the number shown in bold, using once and once only, all six numbers, which accompany it.
You may use any mathematical operations you wish, to arrive at the given number.

            784 1, 1, 5, 6, 8, 100
            327 6, 7, 8, 9, 9, 50
            931 3, 4, 7, 8, 10, 75
            425 2, 4, 6, 8, 9, 50
            489 2, 3, 4, 6, 10, 75
            845 4, 7, 8, 9, 9, 25
            763 2, 3, 4, 5, 6, 25
            599 2, 3, 4, 6, 7, 75
            291 4, 8, 9, 9, 10, 100
            143 1, 4, 5, 6, 9, 10

Is more than one solution possible for a problem? Please include them if you find some.

touche!

In how many ways can you express 1000 using six ones?

No letters like log, sqrt etc Just some of + - / * ^ , concatenation

and brackets. Example 1111-111 - but that's seven ones...
