How many years is 1991 to 2010?

Answer 1

19

Answer 2

To calculate the number of years between 1991 and 2010, you subtract the starting year from the ending year and add 1. So, 2010 - 1991 + 1 = 20 years. This is because both the starting year (1991) and the ending year (2010) are included in the calculation.

Answer 3

Well, honey, if you can count your fingers, you'll figure out that 2010 minus 1991 is 19 years. So, grab a calculator or use those brain cells and do the math - it ain't rocket science!
