Binary numerals are usually read digit-by-digit, in order to distinguish them from decimal numbers. For example, the binary numeral 100 is pronounced one zero zero, rather than one hundred, to make its binary nature explicit, Since the binary numeral 100 is equal to the decimal value four, it would be confusing to refer to the numeral as one hundred.

First Decimal Place:
Let us take a number, 19.7.
1 indicates place value ten.
9 indicates place value one.
7 indicate 7/10(tenths decimal place)
Example problems for first decimal place:
Example 1:
Calculate the following 15.9+15.7-0.15+0.1
Solution:
Given that, 15.9+15.7-0.15+0.1
Numbers of digits behind decimal point are equal.
Step 1: Adding positive numbers,
= 15.9+15.7+0.1
= 31.7.
Step 2: Negative integer add to the primary step
= 31.7 – 0.15
= 31.55
The solution is 31.55
Example 2:
Calculate the following 18.2+0.1-18.7+1.8
Solution:
= 18.2+0.1-18.7+1.8
Numbers of digits behind decimal points are equal.
Step 1: Adding positive numbers,
= 18.2+0.1+1.8
= 20.1
Step 2: Negative number add to the first step
= 20.1– 18.7
= 1.4
The solution is 1.4
Addition for first decimal place:
Problem 1:
Add the following 1.3+1.5+1.7+1.9
Add the positive value,
=1.3+1.5+1.7+1.9
= 6.4
The solution is 6.4
Problem 2:
Add the following 1.6+1.5+1.7+1.7
Add the positive value,
=1.6+1.5+1.7+1.7
=6.5
The solution is 6.5
