(6+5-10)*(9-8) = 1
10*10 - 10 + 10/10 = 100 - 10 + 1 = 91
Use the following [Euro]cent coins: 10 + 5 + 1 10 + 2 + 2 + 2 10 + 2 + 2 + 1 + 1 10 + 2 + 1 + 1 + 1 + 1 10 + 1 + 1 + 1 + 1 + 1 +1 5 + 5 + 5 +1 5 + 5 + 2 + 2 + 2 etc.
1x1 + 1x1 + 1x1 + 1x1 + 1x1 = 5
Here is one way: (1 + 32)*(5-4)
10 10 10 5 5 10 5 1 1 1 1 1
5+5+(-1)+1
It can be done as: -10+1^5 = -9
add 9 plus 5 than subtract 1 from 5 to add it to 9 will give you 10
Now is that $180 or $1.80 cause you can't use 22 coins to make $180 dollars. As for 22 coins to equal $1.80 just use: (each number represents coin denomination) 25, 25, 25, 25, 25, 10, 10, 5, 5, 5, 5, 5, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 = $1.80
1 add 4 is 5 and 2 add 3 make 5. 5 add 5 make 10 so 2 x 10 is 20
5 + 5 - 5 - 5 + 5 + 5 = 10 (5 + 5) x 5/5 x 5/5 = 10
