You can only find truth with logic if you have already found truth without it.

As a toddler when I looked at my fingers and wondered, you helped me to count numbers. As a kid when I looked at stars with awe, you helped me and told that's infinity. As a teen when my confused mind often went blank, you told that's zero and eventually

M4Math helped me a lot.

Thanks m4 maths for helping to get placed in several companies.
I must recommend this website for placement preparations.
