For mathematical operations reasoning plays an important role. If you are good in reasoning skills then it is easy to do basic mathematical operations quickly. There are different topics in maths, like arithmetic, geometry, trigonometry, advanced mathematics. But for every sections it basic steps are always similar . Is that to calculate about the steps and examine how it comes. For that we can utilise our reasoning skills. Reasoning skills include the comparison, arrangements, solutions, speedy operations etc. Through achieving good reasoning and mental ability it is easy to do maths easily.
We have a good mental ability but we always use pen and paper method for solving the problems. So we don't able to find about our mental ability. For that we can do some mental calculations with out using pen and paper or any calculating devices. Just multiply or substrates any number which is not in one digits. At first it takes time. Later by practice we can able to strengthen our mind for calculation. Regularly we are skilled to find out the answer within a glance.
