1+2-3+1-3+9-1+2-1

7

This is the way you can easily do it

1- First add all positive integers
2- sum of positive integer 1+2+1+9+2 = 15

3- Second add all negative integers
4- sum of all negative integers = -3-3-1-1 = -8
5- finally 15-8 = 7
6- that is answer

-
Look for ways to divide it up which makes it easier.

1+2-3+1-3+9-1+2-1 =

(1+2-3) + (1-3+9) + (-1+2-1) =

0 + (10 - 3) + 0 =

You should be able to finish it off now.

Copy-Paste on Google xD

Check the source.

Add the positives subtract the negatives

1+2-3+1-3+9-1+2-1=7
=7

I guess the answer is 7

square root of 49
