Answer: m+n-mn</h3>
You can write mn as m*n
=================================
Explanation:
The sum is the result of adding two or more numbers. Saying the sum of m and n means m+n.
Then we subtract off the product of m and n. The product is the result of multiplying m and n. We say m*n or mn to indicate their product.
Overall, we end up with m+n-mn
Since the order of elements doesn't matter, we use the formula for combination as follows.
So the number of ways to choose 2 elements from a set of 4 elements would be
Thus the answer is 6.
