What is the difference between:

X tambah Y X dengan Y X dan Y

?

PixelSnader,

X tambah Y -> X is added to Y ("X + Y", it is mathematical addition). For a more formal way, we say it, " X ditambah Y".

X dengan Y -> X is with Y (or did you want to say, "X sama dengan Y" ? This will be, "X = Y")

X dan Y -> X and Y (or "X & Y" so then it becomes a boolean equation)

so what was wrong with satu dan tiga?

No numbers accepted? Before accepted? Strange
