if you write the numbers in english words and than subtract the total number of alphabets in both the word, you will get the answer
for example
three – two = 2
sixteen – ten = 4
one hundred seventeen – ninety nine = 19 – 10 = 9
so
one thousand – two hundred sixty five = 11 – 19 = -8
If 1 + 4 = 5, then 8 + 11 = ?

its
(first number * second number) + first number
so
8 + 11 = 8*11 + 8 = 88 + 8 = 96
(first number * second number) + first number
so
8 + 11 = 8*11 + 8 = 88 + 8 = 96
IF 11×11 = 171

by following that:
121/8 = 15 R 1
15/8 = 1 R 7
read here on how to convert one number from 10 base to another base
by following that:
121/8 = 15 R 1
15/8 = 1 R 7
= 1*8^2 + 7*8^1 + 1*8^0 = 171
thus 15×15 = 225
225/8 = 28 R 1
28/8 = 3 R 4
= 3*8^2 + 4*8^1 + 1*8^0 = 341

Fill in the check
I cashed a check
By mistake the cashier gave me cents instead of dollars and dollars instead of cents. I spent five cents on the way home, and then discovered that i possessed exactly twice the amount of the check. What was the exact amount on the check ?
this puzzle is shared by leonard henderson on our facebook page
Check your answer:-
lets assume the amount in the check was x dollars and y cents
though he received y dollars and x cents
though he received y dollars and x cents
after spending 5 cents, his money is twice the amount on the check, i.e. 100y+x -5 = 2(100x + y)
98y = 199x + 5
we need to find two numbers in the exact multiple series of 98 and 199 which differs by 5.
98’s multiple series: 98,196,294,392,490,588,686,784,882,980,1078,1176,1274,1372,1470,1568,1666,1764,1862,1960,2058,2156,2254,2352,2450,2548,2646,2744,2842,2940,3038,3136,3234,3332,3430,3528,3626,3724,3822,3920,4018,4116,4214,4312,4410,4508,4606,4704,4802,4900,4998,5096,5194,5292,5390,5488,5586,5684,5782,5880,5978,6076,6174
199’s multiple series: 199,398,597,796,995,1194,1393,1592,1791,1990,2189,2388,2587,2786,2985,3184,3383,3582,3781,3980,4179,4378,4577,47764975,5174,5373,5572,5771,5970,6169,6368,6567,6766,6965,7164,7363,7562,7761,7960,8159,8358,8557,8756,8955,9154,9353,9552,9751,9950
98*63 = 199*31 +5
thus the amount on the check was 31 dollar and 63 cents.

Here is the best explanation by one of the reader Lee Mann
By row:
8 x 3 = 24. Divide by 6 = 4
9 x 4 = 36. Divide by 6 = 6
12 x 2 = 24. Divide by 6 = 4By column:
8 x 9 = 72. Divide by 6 = 12
3 x 4 = 12. Divide by 6 = 2
4 x 6 = 24. Divide by 6 = 4
8 x 3 = 24. Divide by 6 = 4
9 x 4 = 36. Divide by 6 = 6
12 x 2 = 24. Divide by 6 = 4By column:
8 x 9 = 72. Divide by 6 = 12
3 x 4 = 12. Divide by 6 = 2
4 x 6 = 24. Divide by 6 = 4
I agree that if you work in columns then by adding the first two numbers and subtracting 5 then you get an answer of 5 as explained by various people above. However, if you work by row and add the first two numbers then subtracting 5 won’t work [you need to subtract 7] to get the final number.
Multiplying the first two numbers and then dividing by 6 works horizontally and vertically.

2✖2= 4
4✖4=8
8✖8=64
64✖64 =4505.6
