Which term describes a math problem that shows an equals sign and the result, like 9 - 4 = 5?

• A. Number sentence
• B. Expression
• C. Inequality
• D. Term

Answer: (A)

Think about what a math statement looks like when you see an equals sign. It shows that two sides are equal and includes the result. That’s a number sentence. In the example 9 - 4 = 5, you have a left side (the subtraction) and a right side (the value 5) connected by the equals sign, forming a complete statement of equality. An expression like 9 - 4 is just something to calculate and doesn’t state that two sides are equal. An inequality uses < or > to compare sides and isn’t about equal values. A term is just a single number or variable. So the form with an equals sign and a result is a number sentence.
