## Questions & Answers

### Q: How do you simplify algebraic expressions using the distributive law?

To simplify algebraic expressions using the distributive law, you multiply the variable outside the parentheses with each term inside the parentheses, and then combine like terms.

### Q: How do you find the value of an algebraic expression for a specific variable?

To find the value of an algebraic expression for a specific variable, substitute the value of the variable into the expression and simplify.

### Q: Can you explain the process of subtracting one algebraic expression from another?

To subtract one algebraic expression from another, you first simplify both expressions and then change the signs of the terms in the expression that is being subtracted. Finally, add or subtract like terms.

### Q: What is the purpose of the distributive property in simplifying algebraic expressions?

The distributive property allows you to distribute or multiply a value to each term inside parentheses, simplifying the expression by combining like terms.
