On a calculator display, some years look the same upside down as right side up. What is the first such year in the 21st century?

The first such year is 2002.

Step-by-step explanation:

For them to be the same upside down as right side up, the first and last digit have to be the same.

Since we are in the 21st century, and the years begin with 2, then have to end with 2. So

2xx2.

Numbers that look the same upside down as right side up are: 0,1,2,5,8. So, the first possible year is:

2002

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

can you make your screen more see able?

then i might be able to .
