Examples of Number Sentence
 If there are 5 candies and the cost of each candy is 12 cents, then the cost of 5 candies in the form of a number sentence is written as:
5 � 12 = 60, i.e. the cost of 5 candies = 60 cents.  The cost of 1 apple is $2 and the cost of 7 apples is $14. So, the number sentence that represents the situation is 7 � 2 = 14.
Solved Example on Number Sentence
Ques: Which of the given number sentences is true?
Choices:
A. 40 + 20 <>B. 8 � 4 = 22
C. 40  20 = 18
D. 40 � 8 = 15
Correct Answer: A
Solution:

Step 1: An inequality also represents a number sentence. So,
40 + 20 < 80="">
60 < 80="" is="">
Step 2: 8 � 4 = 32 but the number sentence given 8 � 4 = 22 is not true.
Step 3: 40  20 = 20 but not 18 and hence the number sentence 40  20 = 18 is not true.
Step 4: 40 � 8 = 5 but not 15 and hence the number sentence 40 � 8 = 15 is also not true.
Step 5: Hence the number sentence 40 + 20 < 80="" is="">
