We have learned +, -, *, / four operations. It is now stipulated that "※" is a new operation, A※B=(A+2)(B-1). Such as: 3*5=(3+2)*(5-1)=20. Then 9*10=how much.
我们学过+、-、*、/四种运算．现在规定"※"是一种新运算，A※B=(A+2)(B-1)．如：3※5=(3+2)*(5-1)=20．那么9※10=多少．
<gadget id="calculator">9 + 2</gadget>

<gadget id="calculator">10 - 1</gadget>
<output>9</output>

<gadget id="calculator">11 * 9</gadget>
<output>99</output>

<result>99</result>
