    999999^2 + 999999 + (999999+1)
    Let, 999999=x
    x^2 + 2x + 1=(x+1)^2
    sq root of (x+1)^2 is (x+1)
    The answer is 1 000 000

    (999999*2 + 1999999)*1/2
    (999999*2 + 1000000+ 999999)*/12
    (999999*2 + 999999 + 1 + 999999)*1/2)
    999999 - X Lesa ganin
    (X*2 + 2x +1)*1/2

    [(10^6-1)^2 + 2×10^6 -1]
    [10^12 + 1 - 2×10^6 +2×10^6 -1] = [10^12]
    [10^12]^(1÷2) = 10^6

    999*999 + 999+999+1
    999( 999+1) + (999+1)
    1000*1000
    1000 වර්ගය හැදෙනව නම් වර්ග මූලෙට වර්ගෙ කැපෙනව.
    මං බින්දු අඩුවෙන් හැදුවෙ කම්මැලි නිසා
    එතකොට හරි බින්දු ගාණ දැම්මම
    1000000.

    999,999^2 + 1,999,999
    (1,000,000 - 1)^2 + (1,000,000 + 999,999)
    10^{12} - 2,000,000 + 1 + 1,000,000 + 999,999
    (10^6)^2 - 2,000,000 + 2,000,000
    (10^6)^2 [වර්ගමූලය දැමූ විට වර්ගය ඉවත් වේ]
    10^6 = 1,000,000
