## Definition of Number Sentence

A Number Sentence represents an equation that includes numbers and operation symbols like addition, subtraction, multiplication, and division.

### More About Number Sentence

• A number sentence can also be represented by using inequality symbols like < ,="">.

### 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

#### Solution:

Step 1: An inequality also represents a number sentence. So,
40 + 20 <>
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="" true.="">
