Numerical computation refers to applying the basic principles of arithmetic for solving mathematical questions. This includes problems with basic arithmetic like addition, subtraction, multiplication, and division. The numerical computation notes for GATE PDF has numerical reasoning and quantitative ability. It includes a wide range of mathematical terms like percentage, ratios, powers, fractions, roots, exponents, decimals, numbers, etc. The numerical computation MCQs for GATE CE are an essential interdisciplinary aspect of GATE CE and hold a significant weightage in the Civil Engineering (CE) GATE Exam.

## Important Numerical Computation Topics for GATE CE

The numerical computation syllabus for GATE mostly includes topics from mathematics and statistics and is a sub-set of numerical ability. Here are the most common topics on which questions are asked.

 Topic Explanation Ratio The ratio is a mathematical expression that helps in representing the relationship of two or more numbers. It is mostly expressed in the form of units or a fraction of the total value or percentage of the total number. Percentage The percentage is a ratio or number expressed as a fraction of 100 and depicted by the symbol of %. The Percentage can be calculated by dividing a number by whole value and multiply by 100. Powers and Exponents The powers in mathematical terms show repeated multiplication of the same number. For example – 25 means 2 raised to the power of 5, which means 2 x 2 x 2 x 2 x 2.The exponents help find how many times a number should be multiplied by itself to get a particular result. Permutation and Combinations The numerical computation GATE questions include permutation and combinations. It is the grouping of numbers or objects by placing them in a set and forming subsets. A permutation is selecting the data or object from a group, and a combination represents their order of representation. Series The series is the sum of an infinite sequence of numbers. It includes different types of arithmetic series.

The numerical computation GATE syllabus is versatile, and it includes different types of arithmetic questions. The above five topics are the most important while preparing for numerical computation for GATE CE.
