Question

math class 7 simplify the following (1) -18+12-(-4)+(-16)​

Answer 1

$\large\sf\underline{Given\::}$

• $\sf\:-18+12-(-4) +(-16)$

‎

‎

$\large\sf\underline{To\::}$

• Simplify the given expression.

‎

‎

$\large\sf\underline{Solution\::}$

‎

Following BODMAS rule :

‎

$\sf\:-18+12-(-4) +(-16)$

‎

• Simplifying the brackets

‎

$\sf\implies\:-18+12+4 -16$

‎

• Arranging the -ve and +ve numbers together

‎

$\sf\implies\:12+4-18 -16$

$\sf\implies\:16-18 -16$

$\sf\implies\:-2 -16$

$\large{\mathfrak\red{\implies\:-18}}$

BODMAS rule states that in an expression containing multiple arithmetic operations , there is an order in which they are to be solved.

The order for solving them is provided by BODMAS. The order is as follows :

• B which means simplification of brackets

• O order or exponents

• D for division

• M for multiplication

• A for addition

• S for subtraction
