Mathematics is an effective method of encouraging logical reasoning and building mental discipline. It will undoubtedly help you in your career and increase your problem-solving skills. Many bank exams consist of quantitative reasoning questions. After all, there are different mathematics concepts, one of which is a simplification. As the name suggests, simplification helps simplify mathematical problems with various types, such as BODMAS, decimals, fractions, etc. Some problems can be tricky, and it is essential to practise them daily. You can download 1000 simplification questions pdf online from bank exam preparation platforms. In this article, you will learn more about the different types.
BODMAS: BODMAS stands for Brackets, Order, Division, Multiplication, Addition, and Subtraction. So, you will have to follow this particular order while solving the mathematical operations. The creator of the BODMAS rule is the mathematician Achilles Reselfelt. When using this rule, you will have to solve the brackets first. After that, you will have to solve the square root or square of the number. You must divide, multiply, add and subtract as per the order. You must remember that the order for multiplication, division, addition and subtraction must be completed from the left side to the right side. This rule is necessary because it helps to determine the mathematical operations that require to be performed. For instance, an expression like 4+6-8×5 might baffle any student. But thanks to this rule, it helps simplify the entire operation. And the mnemonic allows the students to remember the proper order the calculations have to be performed. Many students learn this rule before beginning algebra. It is one of the easiest simplification methods and mathematical operations.
Decimals and fractions: Decimals comprise a fractional and whole part. After all, you can get decimals while you break a whole part into smaller ones. For instance, if you have one and a half pizzas, you must write it as 1.5 pizzas. Decimals are required in your daily life because it helps deal with length, weight, money, etc. They are used in places where you don’t want to provide whole numbers. Hence, it allows you to give a precise number while calculating. Even if you weigh yourself, your weight can be shown in decimals. For example, your weight can be 65.4 in decimals. You also need to add, multiply, divide and subtract the number after the decimal point. When it comes to fractions, they have two parts: the numerator and the denominator. You might get fractions in a mixed fraction form; it will allow you to convert them into a fraction and simplify them. The fraction and integral parts are not added together when you simplify them.
Surds and indices: Surds consist of root functions implied for any numerical values, whether a cube root, square root or any other root. There are different types of surds such as simple, pure, similar, compound and mixed. Simple surds consist of a single number, whereas pure surds don’t comprise rational factors, making them irrational. If the surd has a common root factor, it is called similar surds. It is called compound surds when you add or subtract two or more root functions or surds. An actual number with a coefficient outside the root, making them partially irrational, is called mixed surds. The singular form of indices is the index, an exponent or power raised to a variable or number. One law of indices states that if the index consists of a negative value, it will be shown as the positive index’s reciprocal raised to the variable.
