Addition combination of decimal and whole number Tricks
Example 1:
3.3 + 3.33 + 3.333 + 3.3333=?
The result of the addition is 3.3 + 3.33 + 3.333 + 3.3333 = 13.2963.
Shortcut Tricks
Step 1: At First we can calculate the Decimal number 3 ( 0.4321 ) = 1.2963
Step 2: In Step 2 we can calculate the Whole number that is maximum number of 3 digits is
= 3+3+3+3 So, 3 x 4 = 12
Step 3: Now we can add both results of Step 1 and Step 2 = ( 1.2963 + 12 ) = 13.2963.
Example 2:
5.5 + 5.55 + 5.555 + 5.5555 + 5.55555
The result of the addition is 5.5 + 5.55 + 5.555 + 5.5555 + 5.55555 = 27.71605.
Shortcut Tricks
Step 1: At First we can calculate the Decimal number 5 ( 0.54321 ) = 2.71605
Step 2: In Step 2 we can calculate the Whole number that is maximum number of 5 digits is
= 5+5+5+5+5 So, 5 x 5 = 25
Step 3: Now we can add both results of step 1 and Step 2 = ( 25 + 2.71605 ) = 27.71605.
Example 3:
7.7+7.77+7.777+7.7777+7.77777+7.777777
The result of the addition is 7.7+7.77+7.777+7.7777+7.77777+7.777777 =46.580247.
Shortcut Tricks
Step 1: At First we can calculate the Decimal number 7 (4.580247 ) = 4.580247
Step 2: In Step 2 we can calculate the Whole number that is maximum number of 7 digits is
= 7+7+7+7+7+7 So, 7 x 6 = 42
Step 3: Now we can add both results of Step 1 and Step 2 = ( 42 + 4.580247 ) =46.580247.
