Just as physical exercise is important for our body, mental exercise is important for our brains to be quick and active. Solving puzzles and calculating sums forms a part of the mental exercise. In an attempt to get the children to give enough stimulation to their brains, Divesh Shah has specially designed set of exercise papers, each containing twenty questions to be attempted in seven minutes.

The question sets are segregated age-wise and are used to determine the calculating abilities of children. The teachers and parents can use the results to correct the basics of the children taking maxercise. Solving these carefully laid out questions helps students to work on their speed and ability to calculate single digit as well as multiple digit numbers.

The maxercise book compiled by Divesh Shah contains 365 question sets of 20 questions each, one to be solved each day of the year. Shah opines that a maxercise a day boosts the confidence of student who solves it. These exercise papers are set in such a way that the students can learn concepts in stepwise and gradual manner.
