In our previous discussion, we have differentiated Numbers from Real Numbers and discussed its five equalities. This time, we will be tackling the significant figures, digits and place values, and rounding off of numbers.
What is a Significant Figure?
From the word "significant" itself, it is the most important and valued figure of a given number or answer. Take a look with this:
The significant digits in a number include the leftmost, non-zero, and digits to the rightmost written. Examples:
Digits and Place Value
We are all familiar with the words "tens", "hundreds", "thousands" etc., they are called as the digits and place value.
For the given digit above, the corresponding place value of 8 is millions while 7 is hundred thousands. On the other hand, 3 is ten thousands while 9 is thousands. And also, 4 is hundreds, 6 is tens and 5 is the unit digit.
As for given number above, 6 is the unit digit. On right side are: 1 is tenths, 8 is hundredths, 7 is thousandths, 5 is ten thousandths, 2 is hundred thousandths and 3 is millions.
Rounding Off of Numbers
Rounding in Mathematics means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Take a look at this:
That's all folks! I hope you learned something today. My initiative here is to explain Mathematics in the simplest way of my own understanding.
