A number sentence is a mathematical sentence, made up of numbers and signs.The expressions given in examples indicate equality or inequality.A number sentence can use any of the mathematical operations from addition, subtraction, multiplication to division. Symbols used in any number sentence vary depending upon what they indicate.Number sentences can be true or they may not be true.

For example:

10 + 5 = 15. Here we are using the = sign which indicates a balance of both sides.

However, there could also be number sentences which say:

12 + 6 = 9 is not true, but 12 + 6 = 18 is true.

Therefore, a number sentence does not necessarily have to be true. However, every number sentence gives us information, and based on the information provided; it is possible to change the statement from false to true.

So, a number sentence contains numbers, mathematical operations, equal to or inequality sign and a number after the equality or inequality sign. If we remove any of these components, it will no longer be a number sentence.
