Sample Response: Replace keywords with variables, numbers, and operations. “A number squared” is a power where the base is the variable and the exponent is 2. “Decreased by ten” means you must subtract 10 from the squared number.

Numerical expression: 59-34*6 Algebraic expression: 5x-3x+2 A numerical expression is limited to only numbers and can always be simplified to one number. An algebraic expressuion uses terms, more specifically a variable like x, and a constant like 2.
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.

Sample Response: Replace key words with variables, numbers, and operations. More than is addition, product is multiplication, and decreased by is subtraction. The constants are 1, 7, and 5. The expression is 1 + 7n – 5. To evaluate the expression, substitute 6 in for the variable, and then use order of operations to simplify. The value when n = 6 is 38.
a number or algebraic expression by which another is exactly divisible. In the sentence 3 x 4 = 12, 3 and 4 are factors of 12.
You will have to explain what the leap-frog puzzle is. It sounds like it might be interesting!
explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
Factors are the building blocks of integers. Factors make up integers the way letters make up words. A factor is a number or algebraic expression by which another is exactly divisible.
In algebraic expressions, the keyword "1x-9" represents a linear equation with one variable (x) and a constant term (-9). This expression is significant because it helps to simplify and solve equations by isolating the variable and finding its value.
You can always write a numerical division expression as a decimal.
A rational expression is an expression that contains a radical, i.e., a root.
