I thought it was a little more tricky and I keyed in on the word equation. I used only 1 digit 8 times, but came up with 5x+5x+5x+5x+5x+5x+5x+5x=1000 and x=25. I only used the same digit but added a numeric! Oh well… I thought it was clever.

Stuart–you only used (7) 1’s, not 8. I had figured it with 8, but did it this way:

1111 – 111 x 1 = 1000.

Clearly superior solution to the 8’s since it uses fewer operators ;^)

How about 1111 – 111 = 1000 where the minus sign is a 1 turned on it’s side? No plus signs required

Either way too easy, or my brain actually fired up today… Naw… Just way too easy….

I misread the instructions at first, too. I came up with 33+33+33+(3/3)=100. I was a little discouraged when I saw I had to get to 1,000, but I did get it right before I looked at the answer!

grrr…why do Always do things the hard way. I was thinking

2(22^2)+2(2^(2+2))=1000

Except for the parentheses, it can be written in longhand without any mathematical punctuation.

Argh! I didn’t follow the directions carefully. I spent 10 minutes driving myself nuts. I was trying to creat 8 different combinations that add up to 1000. I.E. 888+88+8+8+8+8+8+8. I saw I hit a thousand, but then I passed it!

done with ease – 888+88+8+8+8=1000
