Question

Sum of the numbers m and n decreased by their product; write the algebraic expression​

Answer 1

Answer:   m+n-mn

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
