Xena started with the number googol (1 with a 100 zeros after it). She multiplied it by 8, then added 8 to the result. She then squared that number, and divided what she got by 1 more than a googol. She then divided by 8, and divided by 8 again, and subtracted a googol from her result. What is her final result? 10. What is the sum of the first 100 odd numbers? Algebra 7th Grade 1.
