Arre, in algebra, coefficient toh mane simply "how many" of that x you have—like 3x means three *x*s, just like I stock three gold frames versus five wooden ones. But 3x and 2x² can't add directly because one is like a photo size and the other is a full album—different *purerokom* things. It's like when a customer brings a tiny school sketch and a big canvas; I can't use the same frame for both, na? You have to sort them by kind.
