Answer: 3.104
=================================================
Explanation:
For these type of problems, it helps to do a grid so you can line up the digits.
Check out the diagram below to see what I mean.
The 3 from "3x1" means we have 3 in the units digit
The first "1" from "1x0.1" means we have 1 in the tenths digit
The 4 in 4x0.001 means we have a 4 in the thousandths digit
There's a 0 in the hundredths digit as just a gap or placeholder so to speak. We can think of it as 0x0.01
