All in one post on quants.. ➕➖✖➗ MULTIPLICATION: Multiplication using multiples 12 x 15 = 12 x 5 x 3 = 60 x 3 = 180 Multiplication by distribution 12 x 17 = (12 x 10) + (12 x 7) ---> 12 is multiplied to both 10 & 7 = 120 + 84 = 204 Multiplication by "giving and taking" 12 x 47 = 12 x (50 - 3) = (12 x 50) - (12 x 3) = 600 - 36 = 564 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 14 x 10 = 140 ---> added one zero Multiplication by 50 ---> take the half(0.5) then multiply by 100 18 x 50 = (18/2) x 100 = 18 x 0.5 x 100 = 9 x 100 = 900 Multiplication by 100 ---> move the decimal point two places to the right 42 x 100 = 4200 ---> added two zeroes Multiplication by 500 ---> take the half(0.5) then multiply by 1000 21 x 500 = 21/2 x 1000 = 10.5 x 1000 = 10500 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 333 solve 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, = 1575 75 x 85 first term = (8 + 1) x 7 = 63 last term = 75 combining first and last terms, = 6375 15 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 25 75 x 75 first term = (7 + 1) x 7 = 56 last term = 25 answer = 5625 ---> 75 squared DIVISION: Division by parts ---> imagine dividing $874 between two persons 874/2 = 800/2 + 74/2 = 400 + 37 = 437 Division using the factors of the divisor: "double division" 70/14 = (70/7)/2 ---> 7 and 2 are the factors of 14 = 10/2 = 5 Division by using fractions: 132/2 = (100/2 + 32/2) ---> break down into two fractions = (50 + 16) = 66 Division by 5 ---> divide by 100 then multiply by 20 1400/5 = (1400/100) x 20 = 14 x 20 = 280 Division by 10 ---> move the decimal point one place to the left 0.5/10 = 0.05 ---> 5% is 50% divided by ten Division by 50 ---> divide by 100 then multiply by 2 2100/50 = (2100/100) x 2 = 21 x 2 = 42 700/50 = (700/100) x 2 = 7 x 2 = 14 Division by 100 ---> move the decimal point two places to the left 25/100 = 0.25 Division by 500 ---> divide by 100 then multiply by 0.2 17/500 = (17/100) x 0.2 = 0.17 x 0.2 = 0.034 Division by 25 ---> divide by 100 then multiply by 4 500/25 = (500/100) x 4 = 5 x 4 = 20 750/25 = (750/100) x 4 = 7.5 x 2 x 2 = 30 ADDITION: Addition of numbers close to multiples of ten (e.g. 19, 29, 89, 99 etc.) 116 + 39 = 116 + (40 - 1) = 116 + 40 - 1 ---> add 40 then subtract 1 = 156 - 1 = 155 116 + 97 = 116 + (100 - 3) = 116 + 100 - 3 ---> add 100 then subtract 3 = 216 - 3 = 213 Addition of decimals 12.5 + 6.25 = (12 + 0.5) + (6 + 0.25) = 12 + 6 + 0.5 + 0.25 ---> add the integers then the decimals = 18 + 0.5 + 0.25 = 18.75 SUBTRACTION: Subtraction by numbers close to 100, 200, 300, 400, etc. 250 - 96 = 250 - (100 - 4) = 250 - 100 + 4 ---> subtract 100 then add 4 = 150 + 4 = 154 250 - 196 = 250 - (200 - 4) = 250 - 200 + 4 ---> subtract 200 then add 4 = 50 + 4 = 54 216 - 61 = 216 - (100 - 39) = 216 - 100 + 39 = 116 + (40 - 1) ---> now the operation is addition, which is much easier = 156 - 1 = 155 Subtraction of decimals 47 - 9.9 = 47 - (9 + 0.9) ---> "double subtraction" = 47 - 9 - 0.9 ---> subtract the integer first then the decimal = 38 - 0.9 = 37.1 18.3 - 0.8 = 18 + 0.3 - 0.8 = (18 - 0.8) + 0.3 ---> subtract 0.8 from 18 first = 17.2 + 0.3 = 17.5 WORKING ON PERCENTAGES: 30% of 120 = 10% x 3 x 120 ---> it is much easier working with tens (10%) = 10% x 120 x 3 = 12 x 3 = 36 five percent of a number: 5% 360 x 5% = 360 x 10%/2 ---> take the 10% and divide by 2 = 36/2 = 18 360 x 5% = 360 x 50%/10 ---> take the half(0.5) and divide by 10 = (360/2)/10 = 180/10 = 18 ninety percent of a number: 90% 90% of 700 = (100% - 10%) x 700 = (100% x 700) - (10% x 700) ---> 100% minus 10% of the number = 700 - 70 = 630 What is 18 as a percentage of 50? = 18/50 = (18/100) x 2 ---> method: division by 50 (explained above) = 0.18 x 2 = 0.36 = 36% What is 132 as a percentage of 200? = 132/200 = (132/2)/100 = [100/2 + 32/2]/100 ---> solution by "double division" = (50 + 16)/100 = 66/100 = 0.66 = 66% What is 270 as a percentage of 300? = 270/300 = [(270/3)/100] ---> "double division" (using the factors of 300) = 90/100 = 90% What is 17 as percentage of 500? = 17/500 = (17/50)/10 = (17/100) x 2/10 ---> solution using the procedure: division by 50 = (0.17 x 2)/10 = 0.34/10 = 0.034 = 3.4 % percentages close to 100: 95% of 700 = (100% - 5%) x 700 = (100% x 700) - (5% x 700) = 700 - (10% x 700/2) -------> 5% is 10%/2 = 700 - 70/2 = 700 - 35 = 665 percentages less than 10 percent: 3% of 70 = (3/100) x 70 = (70/100) x 3 ---> divide by 100 then multiply the percent value = 0.7 x 3 = 2.1 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 5% = 5/100 = 0.05 = 1/20 6.25% = 6.25/100 = 0.0625 = 1/16 7% = 7/100 = 0.07 7.5% = 7.5/100 = 0.075 10% = 10/100 = 0.1 = 1/10 12.5% = 12.5/100 = 0.125 = 1/8 20% = 0.2 = 1/5 21% = 0.21 25% = 0.25 = 1/4 30% = 0.3 = 3/10 33.33% = 33.33/100 = 0.3333 = 1/3 37.5% = 0.375 = 3/8 40% = 0.4 = 2/5 50% = 0.5 = 1/2 60% = 0.6 = 3/5 62.5% = 0.625 = 5/8 66.66% = 66.66/100 = 2/3 75% = 0.75 = 3/4 80% = 0.8 = 4/5 87.5% = 0.875 = 7/8 100% = 1 125% = 1.25 = 1 1/4 150% = 1.5 = 1 1/2 200% = 2 FRACTIONS: What is three quarters of 80? = 3/4 x 80 = (80/4) x 3 ---> divide by 4 then multiply by 3 = 20 x 3 = 60 How many quarters in two and a half? 2.5/.25 = 10 ---> there are 10 quarters in $2.50 Improper fractions: 3/2 = 1 1/2 = 1.5 = 150% 4/3 = 1 1/3 = 1.3333 = 133.33% ---> useful number for volume of sphere, etc. 9/5 = 1 4/5 = 1.8 = 180% ---> conversion factor for Celsius/ Fahrenheit temperatures V = 4/3 pi * r^3 where: V = volume of sphere r = radius of sphere F = (1.8 C) + 32 where: F = temperature in Fahrenheit C = temperature in Celsius 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 + 9 Answer: 2209 Sequential Inputs of numbers with 8 1 x 8 + 1 = 9 12 x 8 + 2 = 98 123 x 8 + 3 = 987 1234 x 8 + 4 = 9876 12345 x 8 + 5 = 98765 123456 x 8 + 6 = 987654 1234567 x 8 + 7 = 9876543 12345678 x 8 + 8 = 98765432 123456789 x 8 + 9 = 987654321 Sequential 1's with 9 1 x 9 + 2 = 11 12 x 9 + 3 = 111 123 x 9 + 4 = 1111 1234 x 9 + 5 = 11111 12345 x 9 + 6 = 111111 123456 x 9 + 7 = 1111111 1234567 x 9 + 8 = 11111111 12345678 x 9 + 9 = 111111111 123456789 x 9 + 10 = 1111111111 Sequential 8's with 9 9 x 9 + 7 = 88 98 x 9 + 6 = 888 987 x 9 + 5 = 8888 9876 x 9 + 4 = 88888 98765 x 9 + 3 = 888888 987654 x 9 + 2 = 8888888 9876543 x 9 + 1 = 88888888 98765432 x 9 + 0 = 888888888 Numeric Palindrome with 1's 1 x 1 = 1 11 x 11 = 121 111 x 111 = 12321 1111 x 1111 = 1234321 11111 x 11111 = 123454321 111111 x 111111 = 12345654321 1111111 x 1111111 = 1234567654321 11111111 x 11111111 = 123456787654321 111111111 x 111111111 = 12345678987654321 Without 8 12345679 x 9 = 111111111 12345679 x 18 = 222222222 12345679 x 27 = 333333333 12345679 x 36 = 444444444 12345679 x 45 = 555555555 12345679 x 54 = 666666666 12345679 x 63 = 777777777 12345679 x 72 = 888888888 12345679 x 81 = 999999999 Sequential Inputs of 9 9 x 9 = 81 99 x 99 = 9801 999 x 999 = 998001 9999 x 9999 = 99980001 99999 x 99999 = 9999800001 999999 x 999999 = 999998000001 9999999 x 9999999 = 99999980000001 99999999 x 99999999 = 9999999800000001 999999999 x 999999999 = 999999998000000001
