The computation of whole numbers is a part of the quantitative aptitude section asked in the SSC MTS and CGL exams and railway exams. When you master the skill, it hardly leaves any scope for mistakes. To score well in the quantitative aptitude section and computation of whole numbers, you need to brush up the basic math till class 10th and memorize all-important formulas. Remember, rote learning doesn't work with a concept like the computation of whole numbers. Hence, clarity of concept is the key.
To be able to ace the competitive exam, the candidates appearing for SSC and railway examinations need to practice computation of whole number questions rigorously. Why? Because the section around the number system, whole numbers, and simple calculations usually require a strong quantitative aptitude, which can only be obtained if the aspirant understands the basic concepts and is consistent with practice. Therefore, we're going to cover computation of whole numbers tricks to help you master this topic for the SSC CGL, MTS as well as RRB exams.
Important concepts related to the computation of whole numbers
Calculations with Whole Numbers deal with your ability to understand, compute numbers, and overall mathematical skills. This section is one of the most important and scoring parts of the paper. It holds a lot of importance for employers to understand the arithmetic orientation of the candidate and their overall mental capacity to make quick decisions. We all know that the number system consists of various elements, such as:
All counting numbers starting from 1,2,3,4,5…...till infinity. The sum and multiplication product of two natural numbers is always a natural number; however, this doesn't stand are concerning subtraction and division.
All counting numbers, including 0 (zero). These are also commonly called positive/non-negative integers. Like (0,1,2,3,4,5….)
The set of real numbers that consist of all-natural numbers, zero, and their additive inverses. (.....-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5……)
All numbers that can be expressed as a ratio between two natural numbers in the form of fractions are called rational numbers. Like ½, ⅓, ¾, etc. All terminable decimals are also rational numbers.
Numbers can’t be written as fractions, decimals, or ratios. For, e.g. Square roots, unending decimals (0.33333333...etc.), pie, etc.
These are numbers that include all of the above types of numbers. Rational, irrational, natural numbers, whole numbers, and so and so forth
Apart from these, some important factors to consider while preparing for computation of whole numbers are:
- Arithmetic progression,
- Geometric progression
- Divisibility tests of different numbers
- Division and remainder rules
- Basic number system formulae and
- Understanding the properties of numbers
Computation of Whole Numbers Tricks:
On the face of it, the computation of whole number questions look easy, and many people often overlook its importance, thinking that they know the tricks and don't need to practice. However, this is a big mistake because we can often err in the simplest things. Hence, practice and taking it seriously is the key. Computation of whole numbers tricks to become an expert in the number system part of the quantitative aptitude section are
- Develop a meaning of operation by understanding what are the different methods to deal with the computation of whole numbers.
- Be creative and choose the smartest procedure to solve the problems.
- Plan out and choose efficient strategies to attempt the questions on the computation of whole numbers and be consistent with practice.
- Develop proficiency by solving various computations of whole number PDFs that contain questions and answers related to the topic.
- Make mental math an inherent habit. Access the computation of whole numbers pdf available online for this.
- Language is never a barrier in math as there are many papers on the computation of whole numbers in Hindi as well.
Most recommended books for the computation of whole numbers
Some easily available and recommended books to use for mastering the computation of whole numbers are:
NCERT mathematics textbooks for classes 8-10
R.S Aggarwal Math textbooks for classes 8-10
R.D Sharma for class 10th
Vedic math by Pt. Shastri Ramadan
Vedic math tips and tricks often stand extremely useful when dealing with the computation of whole number questions for the SSC MTS exam and also general arithmetic calculations. Computation of whole number questions and answers can be attempted using Vedic math too.
