Math riddle! How can you add eight 8's to get the number 1,000? (only use addition)

OpenStudy (anonymous):

Hmm... good one. Let me think about it for a second...

OpenStudy (julie):

i think we have to join 8s for this

OpenStudy (anonymous):

i can do it with 8

OpenStudy (anonymous):

If you multiply 5 * 8 you get 40, which has the nice property of ending in 0. So I'm thinking there are 5 groups of 8's

OpenStudy (anonymous):

888 + 88 + 8 + 8 + 8= ?

OpenStudy (julie):

i think foolformath is right :)
