Quantitative Aptitude Practice Test: Real Numbers and BODMAS Simplification — Flashcards

Real numbers are numbers that can be used to measure a continuous one-dimensional quantity. They are the union of both rational and irrational numbers. Real numbers can be defined as the union of both rational and irrational numbers. They can be both positive or negative and are denoted by the symbol “R”. All the natural numbers, decimals and fractions come under this category. Real numbers can be positive or negative and are denoted by the symbol “R”. Some examples of real numbers include: 3, Pi, 0.333, −13, 5.

BODMAS stands for “Bracket, Order, Division, Multiplication, Addition, Subtraction. If an expression involves multiple operations, we apply the BODMAS rule. We start by simplifying the terms inside the brackets, beginning with the innermost bracket and working outwards. We then simplify any roots or exponents. Next, we perform multiplication or division from left to right.
