As we dealt in the topic of numbers that each digit in a number has its place value. Now lets revise a little bit:-

As discussed earlier that each number has digits, here we discuss about place value what is it? The answer is:-

Each digit has its value according to its position in number. Consider the number 6275 starting discovering from right, the right digit has the lowest value but as you go to the left the digit value increase from 1 to 10 to 100 to 1000 to 10000 to 100000 etc. but we don’t pronounce as normal like ten, hundred but they are pronounced as follows:- Read More .......

APPROXIMATIONS

ROUNDING OFF NUMBERS

This is the procedure for approximation of any number so that it can be evaluated or read easy. For example you can be given a number with many decimals like 2.564879 or 12.789007 these are very complicated numbers, so in order to make them simple without changing their values approximation is introduced in so that we can read them and evaluate easily. From the given numbers above can be approximated to one decimal place as 2.6 and 12.8. But note that when you approximate any number it is not wrong but the number loose a little accuracy for example when given 5.6421 and round to one decimal place so that it becomes 5.6 and to two decimal places becomes 5.64, 5.64 is more accurate than 5.6  Read More ....

When adding two numbers the result is called "sum or total” example the sum of 2 and 4 is 6

i. e. (2 + 4 = 6).
