I need to balance the equation and show my work. Ex.
N  2.4 = 5
+2.4 = +2.4

N = 7.4
How would I show my work for:
2.3 + 4.09 = N
I know the answer is 6.39 because I add 2.3 and 4.09 but how do I show the work? Thanks

RickP,
For simple addition of two terms, it is usually fine to just show the result. For example:
2.3 + 4.09 = N
6.39 = N
(And if you want, change the sides so that N is on the left)

RickP,
But, if you feel you need to show the addition step, then you could do something like this (the vertical addition will probably not line up here)
2.3 + 4.09 = N
2.3
+ 4.09

6.39
6.39 = N
