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

 

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

 

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

 

Brilliant, aren't they?

And check this symmetrical numbers:

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=123456789 87654321

 

 

12345679 x 9 x 1 = 111111111

12345679 x 9 x 2 = 222222222

12345679 x 9 x 3 = 333333333

12345679 x 9 x 4 = 444444444

12345679 x 9 x 5 = 555555555

12345679 x 9 x 6 = 666666666

12345679 x 9 x 7 = 777777777

12345679 x 9 x 8 = 888888888

12345679 x 9 x 9 = 999999999

thats rather nifty I have to say

[bronze4door]

thats just effort

[Burns]

bet they used a calculator, wusses

[5hane]

please no more numbers

 

try doing A - level maths

[Toby]

Go figure!!

[GT_Jim]

the last set isnt totally correct as it doesnt have an 8 in it

 

but its quite interesting

[Burns]

but its quite interesting

 

it wouldn't work if the 8 was in it

[bigglesmk2]

Made my head hurt

that was my point

[X-pack-Glyn]

thats impressive, but how about this then

 

1 + 1 = 2

 

2 + 2 = 4

 

4 + 4 = 8

 

i did that all myself, no hesitation whatsoever.
