Question 1173627
.
<pre>

"No more than 3" means in this case 0, 1, 2, 3.


Negative numbers are PROHIBITED due to common sense; but 0 is nor prohibited, so I include it.


Based on the said above, the answer is


    {{{C[10]^0}}} + {{{C[10]^1}}} + {{{C[10]^2}}} + {{{C[10]^3}}} = 1 + 10 + 45 + 120 = 176,


if the order of toppings does not matter.
