Is #20+ - 10# positive or negative?

1 Answer

Positive.

Explanation:

Adding a negative number is the same as subtracting a positive one.
So,
#20+(-10)# is the same as #20-10#

#20-10=10#, so the answer is positive.

(The number of positives (20) is more than the number of negatives (10), so the answer will be positive.)
