What is a true number sentence in math?
TRUTH VALUES OF A NUMBER SENTENCE: A number sentence is said to be true if both numerical expressions evaluate to the same number; it is said to be false otherwise. True and false are called truth values. Number sentences that are inequalities also have truth values.

Can you start sentences with numbers?
The MLA Style Center Since you should never begin a sentence with a numeral, you should first try to reword the sentence. If you find it unwieldy to reorder your words, spell out the number: Seventy-six percent of the class barely passed the final, 18% flunked miserably, and 6% burst into tears.
Can a number sentence be both true and false?
A number sentence is the most concrete version of an equation. It has the very important property that it is always true or always false, and it is this property that distinguishes it from a generic equation. Examples include 2 + 3 = 5 (true) and 2 + 2 = 5 (false).
What is the number sentence of the problem?
Number sentence problems can come in the form of word problems, asking the students to write the equation. For example: Mary has 10 strawberries. If Dan gives her 15 strawberries, how many strawberries does Mary have in total?

What property describes the number sentence?
The commutative property of addition states that when adding numbers together the result will stay the same no matter the order.
What is an example of a number sentence?
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. 10 + 5 = 15. Here we are using the = sign which indicates a balance of both sides.
Do number sentences have to be true?
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.
What number sentences should you teach your kids?
Your kids should already be familiar with one type of number sentence: the equation. For example: 4 + 2 = 6. This game is based on inequalities, like 9 > 4 or 3 < 7.
