Let A and B both represent numbers, and stipulate that A△B represents 4 times of A minus 3 times of B, that is, A△B=4*A-3*B, what is the result of calculating 5△6
设A、B都表示数，规定A△B表示A的4倍减去B的3倍，即A△B=4*A-3*B，计算5△6结果为多少
<gadget id="calculator">5 * 4</gadget>
<output>20</output>

<gadget id="calculator">6 * 3</gadget>
<output>18</output>

<gadget id="calculator">20 - 18</gadget>
<output>2</output>

<result>2</result>
