Hello Please could you help me with this question
Find a quick way to add all Intergers (whole Numbers) between 1 and 1000?
I am at secondary school and am 12 years old
How about 'symmetry':
Add 1 and 1000
Add 2 and 999
Add 3 and 998
Do you see a pattern?
How many terms are there?
[Be careful about the middle term]
