CBSE Class 5 Mathematics Revision Worksheet Set 7

Topic : Simplification

Numerical expressions : Numerical expression is the combination of numbers connected by one or more operations ( + , ̶ , × , ÷ and of ) .
For example – (i) 12 + 16 ÷ 8 ̶ 7
(ii) 15 × 5 ̶ 60 ÷ 15 .
On performing the operations involved in an expression , we obtain a value of the expression.
Performing these operations ( + , ̶ , × , ÷ and of ) is called the simplification of the expression.

The order of these operations are –
(i) Division (ii) Multiplication (iii) Addition (iv) Subtraction

Note : Remember the word DMAS .
D means Division ;
M means Multiplication ;
A means Addition ;
S means Subtraction ;
For example : Simplify : 63 ÷ 9 + 12 × 4 ̶ 5
= 7 + 12 × 4 ̶ 5
= 7 + 48 ̶ 5
= 55 ̶ 5 = 50 .

NOTE - ALL QUESTIONS ARE COMPULSORY.
