Question

Solve the equation:-
If $+$ is $÷$, $-$ is $\times$, $÷$ is $+$, $\times$ is-
$36\times 12+4÷6+2-3$

Answer 1

BODMAS stands for Bracket of Division, Multiplication, Addition and Subtraction. Step wise details are as follows

B - Bracket (1st step)

O - Open (2nd step)

D - Division (3rd step)

M - Multiplication (4th step)

A - Addition (5th step)

S - Subtraction (6th step)

Now we will use this principle for the following question

$36\times 12+4÷6+2-3$

Here $+\Rightarrow ÷$

$-\Rightarrow \times$

$÷\Rightarrow +$

$\times \Rightarrow -$

Recarrying all

$[36-12÷4+6÷2\times 3]$

Step 1 - $36-[12÷4]+[6÷2]\times 3$

$=36-3+3\times 3$

Step 2 - $36-3(3\times 3)$

$=36-3+9$

Step 3 - $(36+9)-3$ (Commutative rule)

$=45-3$

Step 4 - $(45-3)$

$=42$
