The odd numbers from 30 to 80 2006-09-21
From Kieran:
If you added all the odd numbers from 30 to 80, would the answer be even or odd? Explain.

I think it would be odd because I used this equation:
(30 x 5)+(40 x 5)+(50 x 5)+(60 x 5)+(70 x 5)+(25 x 5)=1325
I used the numbers for each set of ten -30 to 80 times 5 and the amount of the endings-1,3,5,7,9- added, times 5. Is that right?
