Math calculations are everywhere at the house, in society and on the job, and these calculations include the basic arithmetic operations of maths. By comprehending the basics, such as addition and subtraction, we can be more confident in various perspectives that require the quick calculation of numbers in our heads. For example, when counting change received from the seller after buying the vegetables or fruits, stationary, milk, etc.
The addition is a helpful approach for estimating ‘how many’ if two or more objects are combined. Suppose when we have many collections of equal size, addition is not the most effective method of calculating the total number of things. Multiplicative conditions arise when determining several collections or measurements of equal size, and arrays are an excellent idea to represent this. Also, some division problems occur when we divide a number or a quantity into groups of equivalent size and when we attempt to undo multiplications. In this case, the quotient will be the required quantity. We can apply the multiplication technique in such cases where equal quantities of large numbers to be added since multiplication is alternatively treated as the repeated addition.
Many transactions we deal with in our daily existence involve some of the other arithmetic operations. Sometimes we may need to add, subtract, divide or multiply the numbers to solve that particular problem. These calculations have pros and cons as they may require a calculator while dealing with large numbers. Let’s understand the examples here where we can apply these operations precisely. Suppose five classrooms are there in a school, and each of these classrooms has ten, twenty, thirty, forty and fifty chairs, respectively. Here, the total number of chairs in these classrooms together can be calculated by adding the numbers. If each class has the same number of chairs, we can use multiplication to find the total number.
As mentioned above, division refers to the distribution of a given number or quantity into equal parts. Suppose we are distributing twenty chocolates to five kids, here the number of kids is referred to as the divisor. That means, dividing the number of chocolates with the number of kids gives the count of chocolates to be given for them. Sometimes we may not get a whole number as the result and it will be dependent on the numbers in places of dividend and divisor. If the dividend is the multiple of a number by which it is divided, then we get the quotient as whole number and remainder as 0. In this case, we can get the exact divisions of a quantity.
The above given examples are very basic and frequently observed situations in our daily existence. However, these operations are useful in every field and almost every sector employs those calculations directly or indirectly. These are primary things to grasp and will help to solve different problems in maths as well as real world problems. A strong foundation in practical math is also helpful for more complicated operations, such as adding or subtracting large numbers, decimals, fractions, units of measurement like cm, m, inches, feet, etc. Sometimes that may require a pencil and paper or a calculator instead of mental calculation. Thus, students must learn all these operations to deal with several real-life situations.
