What is Mental Maths?
What is Mental Maths?
Mental Maths refers to the practice of doing calculations in the head without using any calculator, device, or tools. After grasping maths concepts and visualizing numbers, people are able to make correct calculations in their minds without writing down numbers.
Scientific research supports that people who master Mental Maths techniques are more likely to succeed, not just in academics but also in their life...
1) It stimulates brain power;
2) Better understanding of maths concepts;
3) Reduction in errors;
4) Strengthening of visualization power;
5) Mental Maths is challenging and fun!
