Seagram knows that $$1111\times 2222=2468642$$  Which of the following answers should he decide is $$3333\times 4444$$? 
Overseas Competition->Knowledge Point->Calculation Modules->Whole Numbers->Calculation of Multi-digit Numbers
$$14811852$$  It should be noted that the units digit of the product of $$3333$$ and $$4444$$ will be the same as the units digit of the product of $$3$$ and $$4$$, namely $$2$$: this succinctly identifies the correct option as $$14811852$$. Alternatively, the calculation $$3333\times 4444$$ will have an answer that is $$3\times 2$$ times greater than $$1111\times 2222$$. Now we can work out $$2468642\times 6$$ exactly, which is indeed $$14811852$$.
