Question 1.1: Difference between a number sentence and an algebraic
expression
• Number Sentence: A number sentence is a mathematical statement that
includes numbers and operations (like addition, subtraction, multiplication,
division) but does not have any variables. It is typically a complete statement
that can be evaluated to a numerical value.
o Example: 3+5=83 + 5 = 83+5=8
• Algebraic Expression: An algebraic expression contains variables,
constants, and operations. It represents a mathematical phrase that can have
variables replaced by specific values. It doesn't contain an equal sign, so it's
not a complete statement but rather a part of an equation or inequality.
o Example: 2x+42x + 42x+4
Explanation: In the number sentence 3+5=83 + 5 = 83+5=8, all terms are
numbers, and it forms a complete statement that can be evaluated. In contrast, the
algebraic expression 2x+42x + 42x+4 contains a variable xxx and represents a
mathematical phrase rather than a statement with a definitive value.
