Given:

K = 42048 kWh/yr.

The equation is:

Btu = 3412 / kWh

**K kW**

__x__**H**

__x__= 3412 Btu /kWh

**42,048 kWh**

__x__= 143.5

**106 Btu**

__x__That last line appears to leave out something in its left field. It does not even appear to be related to the rest of the equation.

Am I missing something, or does this look to be an error in the book?

Also, what is the general accepted method for posting the multiplication symbol when asking questions like this on this forum?

Thanks.
