Multiplication Tricks
The above mentioned Trick is one of the easiest method for calculation for two digit numbers if you master it. We are here providing few more Math Shortcut Tricks relating to multiplication, try to use most of these tricks to speed up your calculations.
 Multiplication using multiples
12 x 35
= 12 x 5 x 7
= 60 x 7
= 420  Multiplication by distribution
12 x 17
= (12 x 10) + (12 x 7) —> 12 is multiplied to both 10 & 7 (where 10+7=17)
= 120 + 84
= 204  Multiplication by “giving and taking”
12 x 97
= 12 x (100 – 3)
= (12 x 100) – (12 x 3)
= 1200 – 36
= 1164  Multiplication by 5 –> take the half(0.5) then multiply by 10
428 x 5
= (428 x 1/2) x 10 = 428 x 0.5 x 10
= 214 x 10
= 2140  Multiplication by 10 —> just move the decimal point one place to the right
26 x 10
= 260 —> added one zero  Multiplication by 50 —> take the half(0.5) then multiply by 100
46 x 50
= (46/2) x 100 = 46 x 0.5 x 100
= 23 x 100
= 2300  Multiplication by 100 —> move the decimal point two places to the right
36 x 100
= 3600 —> added two zeroes  Multiplication by 500 —> take the half(0.5) then multiply by 1000
42 x 500
= 42/2 x 1000
= 21 x 1000
= 21,000 
Multiplication by 25 —> use the analogy $1 = 4 x 25 cents
25 x 14
= (25 x 10) + (25 x 4) —> 250 + 100 —> $2.50 + $1
= 350 
Multiplication by 25 —> divide by 4 then multiply by 100
36 x 25
= (36/4) x 100
= 9 x 100
= 900 
Multiplication by 11 if sum of digits is less than 10
72 x 11
= 7_2 —> the middle term = 7 + 2 = 9
= place the middle term 9 between 7 & 2
= 792 
Multiplication by 11 if sum of digits is greater than 10
87 x 11
= 8_7 —> the middle term = 8 + 7 = 15
because the middle term is greater than 10, use 5 then
add 1 to the first term 8, which leads to the answer of
= 957 
Multiplication of 37 by the 3, 6, 9 until 27 series of numbers –> the “triple effect”
Solve 37 x 3
multiply 7 by 3 = 21, knowing the last digit (1), just combine two more 1’s giving the triple digit answer 111 Solve 37 x 9
multiply 7 by 9 = 63, knowing the last digit (3), just combine two more 3’s giving the triple digit answer 333Solve 37 x 21
multiply 7 by 21 = 147, knowing the last digit (7), just combine two more 7’s giving the triple digit answer 777. 
Multiplication of the “dozen teens” group of numbers —
(i.e. 12, 13, 14, 15, 16, 17, 18, 19) by ANY of the numbers within the group:
solve 14 x 17
4 x 7 = 28; remember 8, carry 2
14 + 7 = 21
add 21 to whats is carried (2)
giving the result 23
form the answer by combinig 23 to what is remembered (8)
giving the answer 238  Multiplication of numbers ending in 5 with difference of 10
45 x 35
first term = [(4 + 1) x 3] = 15; (4 is the first digit of 45 and 3 is the first digit of 35 –> add 1 to the higher first digit which is 4 in this case, then multiply the result by 3, giving 15)
last term = 75
combining the first term and last term,
= 157575 x 85
first term = (8 + 1) x 7 = 63
last term = 75
combining first and last terms,
= 637515 x 25
= 375  Multiplication of numbers ending in 5 with the same first terms (square of a number)
25 x 25
first term = (2 + 1) x 2 = 6
last term = 25
answer = 625 —> square of 2575 x 75
first term = (7 + 1) x 7 = 56
last term = 25
answer = 5625 —> 75 squared

116 + 39
= 116 + (40 – 1)
= 116 + 40 – 1 —> add 40 then subtract 1
= 156 – 1
= 155116 + 97
= 116 + (100 – 3)
= 116 + 100 – 3 —> add 100 then subtract 3
= 216 – 3

Decimals
To convert or express percentages as decimals, divide by 100 or simply just move the decimal point by two places to the left of the given number, thus:1% = 1/100 = 0.01
 2% = 2/100 = 0.02 = 1/50
 3% = 3/100 = 0.03
 4% = 4/100 = 0.04 = 1/25

Square Number
 Tips 1: 2 Digit Number which ends in 5
Step1: Multiply the first digit of number, with the next to its number. Ex: 35 is the number you want to square. 3 x 4 = 12
Step2: Finally add 25 at the end of the result.Answer: 1225  Tips 2: Any 2 Digit Number
Ex: 47
Step1: Look for the nearest 10 boundary.
3 from 47 to 50
Step2: Since we went up 3 to 50, now go down 3 from 47 to 44.
Step3: Now mentally multiply 44 x 50 = 2200 – 1st answer.
Step4: 47 is 3 away from the 10 boundary 50, Square 3 as 9 – 2nd answer.
Step5: Add the first and second answer, 2200 + 9Answer: 2209
