Hi. you've asked an incomplete question. However, I provided some explanation about algebraic expressions and numerical expression.
Step-by-step explanation:
First, we may wonder: What is a numerical expression? In simple words, they are mathematical expressions that contain numbers and operations (like +, -, ÷, ×).
For example, 7+70, 90-10, 60÷10, 5×4 are numerical expressions.
While an algebraic expression on the other hand is a mathematical expression that contains at least one variable.
Variables are letters or symbols (like x, y, p, q, etc) that represent an unknown number or value in a mathematical expression.
For example, 7x+70, 90y-10 are algebraic expressions since they contain at least one variable.
