Question

The parts of a variable expression that are separated by addition or subtraction signs are called?

• A. Algebraic expression
• B. Numerical expression
• C. Algebraic terms
• D. Like terms

Answer 1

The correct option is C Algebraic terms

Algebraic expressions are mathematical phrases that may contain numbers, operations and variables.
For example, $3x+4y$ is an algebraic expression.

Numerical expression have numbers in them and often operations.
For example, $6+8+2$ is a numerical expression.

The parts of a variable expression that are separated by addition or subtraction signs are called algebraic terms.
For example, in an algebraic expression $4a+5b+2c$, the algebraic terms are $4a$, $5b$ and $2c$.

The terms with same algebraic factors are called like terms.
For example, in an algebraic expression $7x^{2}y+2xy+9x{y}^2-5x^{2}y$, the like terms are $7x^{2}y$ and $-5x^{2}y$.

Therefore, option (c.) is the correct answer.
