LOGITICA: Improve Your Critical Thinking and Problem Solving Skills: The Brain Behind the Brain

Arithmetic puzzles, number patterns, equations, and strategy problems give LOGITICA its distinctive way of exploring critical thinking. Neelabh Kumar builds the book around a simple idea: pay attention to the challenge a problem presents, then develop the reasoning needed to solve it rather than simply memorizing an answer.

Reasoning, one problem at a time

Across 13 chapters, the book moves through formats such as Number Box, Number Cross, Number Sequence, Marbles in a Box, and Brick Wall. Later chapters introduce number pyramids, arithmetic input-output problems, and a strategy challenge. The changing puzzle formats invite readers to look for patterns, test possible approaches, and connect mathematical ideas to the problem in front of them.

From number patterns to equations

The chapter topics span arithmetic operations, prime and Fibonacci numbers, linear and quadratic equations, averages, Pascal’s triangle, functions, and vectors. Worked examples and chapter exercises offer opportunities to follow a line of reasoning and then try problems independently. Summaries help gather the central ideas before the next challenge.

A reference section to revisit

Eleven appendices revisit topics including sums of natural, odd, and even numbers; quadratic equations; binomial expansion; linear equations; functions and sets; and number sequences. An answer section and index round out the book, making it useful to return to particular exercises and concepts.

For curious problem-solvers

LOGITICA may suit readers who enjoy mathematical puzzles and want structured practice with logical and analytical reasoning. Its variety of problem types gives learners a chance to work through different approaches, while its central advice is memorable: build the logic, not the memory.
