A letter to represent an unknown number

• Term

• Coefficient

• Variable

• Expression

Answer explanation

A letter representing an unknown number is called a variable. In mathematics, variables are used to denote values that can change, making 'Variable' the correct choice over the other options.

A letter to represent an unknown number

• Term

• Coefficient

• Variable

• Expression

Answer explanation

A variable is a letter used to represent an unknown number in mathematics. It differs from a coefficient, which is a numerical factor, and an expression, which is a combination of terms. Therefore, the correct answer is 'Variable'.

Parts of an expression separated by a plus or minus sign

• Term

• Constant

• Expression

• Coefficient

Answer explanation

In mathematics, a 'term' refers to parts of an expression that are separated by plus or minus signs. Therefore, the correct answer is 'Term', as it specifically describes these components of an expression.

A mathematical phrase that contains numbers, variables, and operations with no equal sign

• Variable

• Expression

• Equation

• Exponent

Answer explanation

An expression is a mathematical phrase that includes numbers, variables, and operations but does not have an equal sign. In contrast, an equation has an equal sign, making 'Expression' the correct choice.

Click on the name of the red part of the algebraic expression:

4² + 2x -7

• coefficient

• variable

• base

• power

Answer explanation

In the expression 4² + 2x - 7, the red part '2' is the power. It indicates the exponent to which the base (4) is raised. Therefore, the correct answer is 'power'.

Click on the name of the red part of the algebraic expression:

4² + 2x -7

• variable

• constant

• base

• coefficient

Answer explanation

In the expression 2x, the number 2 is the coefficient, which multiplies the variable x. The red part highlights the coefficient, making 'coefficient' the correct choice.
