Explain how to write and evaluate an algebraic expression. one more than the product of a number and seven, decreased by five; evaluate when n = 6
(PS, I'm giving brainliest and its worth 30 points)

This is the correct way to write the expression. Based on the order of operations, always solve operations in parentheses first. Here, you'd add 4 + 2, then multiply that sum by 5—in other words, exactly what was written in the original expression.
