Once in a math class, Teacher Xiao He wrote such a problem on the blackboard for the students to do: There is a division formula, the dividend is 64 more than the divisor, the quotient is 5, and the remainder is 4. What is the dividend? So what is the correct answer for the students?
一次上数学课，小何老师在黑板上写了这么一道题让同学们做：有一个除法算式，被除数比除数多64，商是5，余数是4．求被除数是多少？那么同学们算出的正确答案是多少．
<gadget id="calculator">64 - 4</gadget>
<output>60</output>

<gadget id="calculator">5 - 1</gadget>
<output>4</output>

<gadget id="calculator">60 / 4</gadget>
<output>15</output>

<gadget id="calculator">5 * 15</gadget>
<output>75</output>

<gadget id="calculator">75 + 4</gadget>
<output>79</output>

<result>79</result>
