A natural number is multiplied by itself. Is it possible to have 66 at the rightmost end?

Simple logic for this is :-

for example

11*11=121 (11 is 2 one’s so from 1 till 2 and back )

111*111 =12321 (111 is 3 one’s so count from 1 till 3 and back ) that is 1 2 3 and back 2 1

similarly for 12345678987654321 =111,111,111(9 one’s) *111,111,111

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
