Question

KNOWING OUR NUMBER , what were the difficulties or challenges ? long answer​

Answer 1

Answer:

Counting things is easy for us now. We can count objects in large numbers,

for example, the number of students in the school, and represent them

through numerals. We can also communicate large numbers using suitable

number names.

It is not as if we always knew how to convey large quantities in conversation

or through symbols. Many thousands years ago, people knew only small

numbers. Gradually, they learnt how to handle larger numbers. They also learnt

how to express large numbers in symbols. All this came through collective

efforts of human beings. Their path was not easy, they struggled all along the

way. In fact, the development of whole of Mathematics can be understood

this way. As human beings progressed, there was greater need for development

of Mathematics and as a result Mathematics grew further and faster.

We use numbers and know many things about them. Numbers help us

count concrete objects. They help us to say which collection of objects

is bigger and arrange them in order e.g., first, second, etc. Numbers are

used in many different contexts and in many ways. Think about various

situations where we use numbers. List five distinct situations in which

numbers are used.

We enjoyed working with numbers in our previous classes. We have added,

subtracted, multiplied and divided them. We also looked for patterns in number

sequences and done many other interesting things with numbers. In this chapter,

we shall move forward on such interesting things with a bit of review and

revision as well.
