Question

21-3+18 divided by 6=6

Answer 1

Step-by-step explanation:

we have to do this by bodmas which means first divide 18 by 6 is equal to 3 then add 3 to 3 so 21 -6 is equal to 15 not to 6

Answer 2

Answer:

( 21 - 3 + 18 )/6 = 6

Step-by-step explanation:

• BODMAS rule defines the order of arithmetic operations which are to be operated first.
• B BRACKET
• O OF
• D DIVISION
• M MULTIPLICATION
• A ADDITION
• S SUBTRACTION

Given that :

• LHS = (21 - 3 + 18)/6

Solution :

• LHS = (21 - 3 + 18)/6
• 21 and 18 has positive sign and 3 has negative sign.
• Firstly, doing calculation in bracket.
• Subtracting 3 from 21 we get : 21 - 3 = 18.
• Now, adding 18 in this result, we get : 18 + 18 = 36
• Dividing 36 by 6, we get : 36/6 = 6.

$\frac{(21 - 3 + 18)}{6} \\ = \frac{(18 + 18)}{6} \\ = \frac{36}{6} \\ = 6$

• Hence, LHS = RHS .
