I'm stuck on understanding the concept behind truth tables..Here is an example of a truth table I am trying to build...

M = A'B’C’ + A’B C + A B’C’ + A B’C + A B C

I have the initial part done, however I'm stuck filling in the "M" portion of the table. I have the table built, but huge formating issues when I try to post it. I'll attach the table as a jpg

When you have many inputs, the table becomes huge. For three inputs you have 2^3=8 rows. Now consider four inputs, 2^4=16 rows. Now consider five inputs, 2^5=32 rows, and so on. Do you really want to fill a 32 row truth table by hand? Even on computer it is annoying.
