1.1 Difference between a number sentence and an algebraic expression
Number Sentence: A number sentence is a mathematical statement that contains
numbers and mathematical operations, typically expressing a relationship between
quantities. It does not contain any variables. For example: 3+5=83 + 5 = 83+5=8
10−2=810 - 2 = 810−2=8
These are number sentences because they are statements involving actual numbers
and arithmetic operations.
Algebraic Expression: An algebraic expression contains variables, numbers, and
operations. It represents a mathematical phrase that can include constants and
variables, but does not have an equals sign. For example: 3x+23x + 23x+2 2y−72y
- 72y−7
These are algebraic expressions because they involve variables (like xxx and yyy)
along with numbers and arithmetic operations.
Difference Illustrated:
• Number Sentence Example: 3+5=83 + 5 = 83+5=8
