Expert Solution
Step 1

As ∑is used to denote the sum, similarly, ∏is used to denote the product.

Assume, a be a variable which can take four values such as a1, a2, a3 and a4. Then ∑i=14(ai) denotes the sum of these values, that is, ∑i=14(ai)=a1+a2+a3+a4 and  ∏i=14(ai) denotes the product of these values, that is, ∏i=14(ai)=a1·a2·a3·a4.
