<gadget id="calculator">20 / 100</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">4 * (1/5)</gadget>
<output>4/5 = around 0.8</output>

<gadget id="calculator">(2/5) + (4/5)</gadget>
<output>6/5 = around 1.2</output>

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

<gadget id="calculator">(6/5) / 5</gadget>

multiply(const_100, divide(add(divide(40, const_100), multiply(4, divide(20, const_100))), add(const_1, 4)))
"say morks income is - 100 so tax paid will be 40 say mindys income is 4 * 100 = 400 so tax paid is 20 % * 400 = 80 total tax paid = 40 + 80 = 120 . combined tax % will be 120 / 100 + 400 = 24 %"
