To write the expression x - 10x + 15 in a word phrase, you would say "the difference between x and ten times x plus fifteen." This phrase breaks down the expression into its components: x (the variable), 10x (ten times the variable x), and 15 (a constant value). The word "difference" indicates the subtraction operation between x and 10x, followed by the addition of 15.

Assuming that x and y are two variables, such as they might be in Algebra, and that the expression "xy" is meant to be the multiplication of x times y, you would write it as x * y This expression could be used with a third variable in an assignment statement, or as a condition in an if statement where it can be compared to another variable or a constant.
