What is a number sentence?

A number sentence is a mathematical statement that shows a relationship between numbers using mathematical operations like addition, subtraction, multiplication, division, and sometimes equality or inequality signs.

Here are some examples:

* 3 + 4 = 7 (This sentence states that 3 plus 4 equals 7)

* 5 - 2 < 4 (This sentence states that 5 minus 2 is less than 4)

* 6 x 2 = 12 (This sentence states that 6 multiplied by 2 equals 12)

* 10 ÷ 2 = 5 (This sentence states that 10 divided by 2 equals 5)

Key features of a number sentence:

* It always includes numbers.

* It uses mathematical operations (addition, subtraction, multiplication, division).

* It expresses a relationship between the numbers.

* It can be true or false.

Number sentences are used to represent mathematical problems and to help us understand how numbers interact with each other. They are the building blocks of more complex mathematical equations and expressions.
