Answer 1

2015-1844=171

171 years is between year 2015 and 1844.

Answer 2

To find the number of years between 1844 to 2015 you have to subtract.

Lets say that x is the # of years in between 1844 and 2015

Then we have:
$\sf{2015 - 1844 =x}$

After doing the subtraction using a calculator or a pencil and paper, you get that:

$\huge{\boxed{\bf{x=171}}}$

So 171 years have passed from 1844 to reach to 2015.
