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

Mathematics is like checkers in being suitable for the young, not too difficult, amusing, and without peril to the state.

M4Math helped me a lot.

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