Cyprus: Problem solving, make 100

This is a problem solving activity, all you have to do is add, minus, subtract, times and divide it to make it into a 100 number.  I used for this equation subtract, times and addition. I tried to use the column strategy but it did not work. But the only strategy I used was the jump strategy. It works because you could use those equations and use them for the jump strategy. Thats how I got up with 100 using 1,2,3,5,6,7,8,9 and 10. I worked with Anthony but we both have our own work, we just worked together.
