for instance:
near 10
near 100
near 1000
near 10000
near 100000
near 1000000
near 10000000
and so forth
It is fairly simple.
For instance:
18^2 first take 18 and subtract 10 (the number it's near), this will give you 8.
now add the number you got to the number you are squaring, in this case 18+8=26.
After this square the first number you got, in this case 8, and tack it on to the last spot (after the 6).
8^2 = 64
26+064=
26
064
----
324 <---- tada, you're done.
This can be applied to any other similar instance:
107^2
114
7^2 = 49
114
00049
------
11449 <- that's the right answer
1007^2
1014
0000049
--------
1014049 <- done
Now you notice that we go up by odd numbers for the nulls that we put in. For 10 you put in one null, 100 is 3, 1000 is 5, 10000 is 7 and so forth. Enjoy this pattern, I simply love it!
