To evaluate $$60\div 4+1\times 3$$, we first do the $$\times $$ and $$\div $$ in the order in which they appear. Do the addition last. We get $$15+3=18$$. 
Before I began snacking, there were $$60\div 4+1\times 3$$ gumballs here. If I ate all of them, how many gumballs did I eat? 

(A) $$4$$ 
(B) $$18$$ 
(C) $$36$$ 
(D) $$48$$
