Speed Addition Tricks

The addition is a mathematical operation. It is one of the simplest numerical tasks. The addition is basic in numerical operations. Addition symbol is + (plus). Addition operation performs between two or more numbers. The addition is used in every numerical calculation. Addition operation is simple and everyone knows how to perform addition, I will tell you how to perform addition fast and accurate with addition tricks. Here I will tell you shortcut methods for addition. These are useful for competitive exams especially simplification tricks for bank exams. Next tutorial I will tell you shortcuts for subtraction multiplication and division.
Let’s see,

Trick 1:

Here is a trick that is for near value of 10, 100, 1000, 10000 etc. Just do mind calculation for near value of numbers. It is easy, instead of a regular method. It is also for the 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 long length calculations. It is simple when you add a 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 same number and increasing series, follow this trick. It is for all same and increasing order numbers. Just take a common number and multiply. This type of addition tricks available in Vedic maths. This type addition tricks for large 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:

It is similar to trick 3. The only difference is numbers series is reverse when you add. Just add and multiply with a 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 simpler. First, add unit’s digit then add the total. These are speed addition tricks.

Example: 17 + 6.

17 + 6.      ∴ Separate tens and units.
10+7+6       ∴ Add units 
10+11        ∴ Add total
23

Trick 6:

The addition operation perform between separated suitable digits. Separation of digits done for suitable other 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:

Separation makes calculation simpler. So separate possible numbers then add.

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 found suitable units digit numbers, add those numbers first then 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
