What does the term 'coefficient' mean in algebra?

Back

A coefficient is a numerical factor in a term of an algebraic expression. For example, in 4x, 4 is the coefficient.

Front

What is a 'constant' in an algebraic expression?

Back

A constant is a fixed value that does not change. In the expression 2y + 5, the number 5 is a constant.

Front

How do you identify the difference of two numbers in algebra?

Back

The difference of two numbers is found by subtracting one number from another. For example, the difference of n and 18 is expressed as n - 18.

Front

What does 'evaluate' mean in mathematics?

Back

To evaluate means to calculate the value of an expression by substituting numbers for variables. For example, evaluating b^2 + 4 when b = 3 gives 13.

Front

What is the product of two numbers?

Back

The product is the result of multiplying two numbers together. For example, the product of 15 and c is expressed as 15c.

Front

What is the difference between a variable and a constant?

Back

A variable is a symbol that represents an unknown value, while a constant is a fixed value. For example, in the expression 3x + 4, x is a variable and 4 is a constant.

Front

How do you find the coefficient of a term in an expression?

Back

The coefficient is the number in front of the variable in a term. For example, in the term 7y, the coefficient is 7.
