Sophia: Evaluating Numeric Expressions: Lesson 2

In this substitution and evaluation activity, students solve and complete 22 different problems that include using the substitution method of variables. First, they evaluate each expression for the given variable. Then, students solve...

The same rules apply. While watching the video, learners realize that the same rules apply to evaluate an expression with negative exponents as does simplifying an expression. The presentation shows a set of steps to evaluate a monomial...

All you need to do is two easy steps: substitute and simplify. By viewing a brief YouTube video, scholars see an example of evaluating an expression. This example is in the form (a+b)/(c-d) and requires simplifying a fraction after...

If you hate to evaluate, here's a video that might just change your attitude. Pupils watch a concise YouTube video that shows how to evaluate the expression -7x^2-4y^2-8xy+7. It describes how using parentheses when substituting negative...

These are equivalent, too. The resource presents two expressions to simplify that require using the distributive property and/or combining like terms. After simplifying the expressions, the video shows how to evaluate the expressions to...

What's the value in learning about 3(b^2)r? A brief YouTube video demonstrates how to evaluate the algebraic expression 3(b^2)r. Specifically, scholars find the value of this expression when b = -3 and r = -2.

Evaluate the equivalence of expressions. A helpful video walks through the process of simplifying two expressions. Using values for the variables, the presentation evaluates the original expression and the simplified expression to show...

Numerical expressions contain numbers and mathematical operations. In addition to numerical expressions, algebraic expressions contain not only numbers but also variable(s). Watch this video as the instructor illustrates several examples...

This lesson defines what it means to evaluate an expression. It is 11 of 20 in the series titled "Evaluating an Expression."

Seventh graders use the distributive property to rewrite and solve multiplication problems. Then they apply addition and multiplication properties to simplify numerical expressions.
