when Iam performing modular division on negative numbers,I found that it is not same as in case of positive numbers

I've tried

>>> -123%10
7
>>> 123%10
3

I expected that the output of -123%10 to be 3,but the actual output is 7

That's how it works. Clock analogy: 1 hour after noon (+1pm) is 1:00, 1 hour _before_ noon (-1pm) is 11:00. – tzaman Jul 10 '19 at 18:05
Adding to @tzaman, to solve this you can use `abs(number) % 10`. – Austin Jul 10 '19 at 18:08
