Addition is a mathematical operation. It is one of the simplest numerical operations. Addition is basic in numerical operations. Addition symbol + (plus). The addition operation is done between two or more numbers. Addition is used in every numerical calculation.
The addition operation is very simple and everyone knows how to perform addition, I will tell you how to do addition fast and accurate with addition tricks. Here I will tell you shortcut methods for addition. These are useful for simplified tricks for competitive exams especially for bank exams.
In the next tutorial I will tell you shortcuts for subtraction multiplication and division.
Let's see,
Fast Multiplication Tricks
Trick 1:
Here is a trick for rounding to the nearest value of 10, 100, 1000, 10000 etc. Think about the nearest value of the numbers. This is easier than the usual method. It is also a time-saving trick.
Example: 136+89
136+89 ∴ 89 is near value of 90
136+90-1 ∴ add 90 and 136
226-1 ∴ subtract
225
Trick 2:
This trick is useful for very long calculations. It is very easy when you add decimal and natural numbers separately.
Example: 15.5+8.25
15.5+8.25 ∴ Separate natural and decimal numbers
15+8+.5+0.25 ∴ Add decimal numbers
15+8+0.75 ∴ Add natural
23+0.75 ∴ Add total
23.75
Trick 3:
When you see the same number and increasing series, follow this trick. This is for same and increasing order numbers. Take the common number and multiply it. There are additional tricks like this available in Vedic Math. This type of addition tricks are for larger numbers.
Example: 6+66+666+6666+66666
6+66+666+6666+66666 ∴ take 6 common
6(1+11+111+1111+11111) ∴ Add increasing 1’s, see below result
6(12345) ∴ multiply number with 6
74070
Trick 4:
This is similar to Trick 3 . The only difference is that when you add, the sequence of numbers is reversed . Add and multiply by the common number.
Example: 0.8+0.88+0.888+0.8888
0.8+0.88+0.888+0.8888 ∴ Take 8 common
8(0.1+0.11+0.111+0.1111) ∴ Add increasing decimal 1’s
8(0.4321) ∴ multiply 8 with that decimal
3.4568
Trick 5:
This trick makes calculations easier . First, add the units digit, then add the sum. These are tricks for adding speed.
Example: 17 + 6.
17 + 6. ∴ Separate tens and units.
10+7+6 ∴ Add units
10+11 ∴ Add total
23
Trick 6:
The addition operation is performed between the appropriate digits separated. Separating digits for other suitable numbers.
Example: 74+8
74+8 ∴ Separate unit’s digit suitable for other numbers
74+6+2 ∴ Add suitable number
80+2 ∴ Add total
82
Trick 7:
Division makes calculation easier. So separate the possible numbers and then add them.
Example: 662+579
662+579 ∴ Separate hundreds and tens
600+62+500+79 ∴ Add hundreds
1100+62+79 ∴ Add tens
1100+ 141 ∴ Add total
1241
Trick 8:
If you find the numbers with suitable units digits, add those numbers first and then the other numbers.
Example: 7 + 8 + 3 + 2 + 5
7 + 8 + 3 + 2 + 5 ∴ Add suitable numbers
10+8+2+5 ∴ Add suitable numbers
10+10+5 ∴ Add suitable numbers
20+5 ∴ Add total
25
Trick 9:
What do you do if you don't know addition? Counting numbers, am I right? So instead of 2+7, add 7+2 numbers. This is also useful for counting numbers.
Example: 2 + 7
2 + 7 ∴ Add number 7+2
7+2 ∴ Add total
9
