Yeah but with 5+0=5, just like Add tires to a car that doesn't exist, you still have tires. Tires(5)+Non-existing car(0)=Tires(5)

Its only if you have a problem like
10x1x243473784x5x0x49859x1 then every number wouldn't matter besides the zero. thats the rules with multiplication.

With addition its different, 20 Grand was right about the problem.

Just because you type in numbers into a calc. doesn't mean you'll get the right answer, you must follow the rules math has.
