Since $1.2 \times 1.5 = 1.8$ and $\dfrac{ 0.32}{0.8} = 0.4$ , now subtraction the two values we get $1.8 - 0.4 = \boxed{ 1.4}$

Simple standard approach.

A cute problem with the solution. Thanks for sharing it.

The solution looks better with the latex for mathematical expressions. I've edited your solution. If you're new to latex, you can learn it from Daniel's latex guide .

Thanks. I sometimes remember to use LATEX, and sometimes I don't.

Just wondering, what is the point?

Or are you referring to the decimal point?

I was being punny and referring to all the decimal points.

I thought you meant that you have a point in pointing people to solve this pointing problem with points. I am not sure though. :P
