15 is the answer i divided
It might be 31 if you add all the numbers together but I'm not positive.
Multiply each number one by one
Do long multiplication(google it)
<span>Changing the grouping of the addends should not change the sum, according to the associative property of addition. You might group them differently with (50 + 3) + 47, so that you have 50 + (3 + 47). You might not regroup them with (16 + 4) + 5 rather than 16 + (4 + 5).</span>
