We can use the mnemonic PEMDAS - Parenthesis (or bracket) - Exponent - Multiplication - Division - Addition - Subtraction with the note that multiplication / division have the same order and addition / subtraction have the same order.
The way that the equation was written; it can be interpreted in 2 ways:
A. 6
---------
2 (1+2) OR
B. 6
-------- X (1+2)
2
when we used the slash sign it is not clear if the numerals(1+2) inside the parenthesis is part of the divisor or if it is part of the dividend:
6 = dividend
------
2 = divisor
If (1+2) is part of the divisor then we can use equation A where in the answer will be
6 6 6
--------- = ---------- = ------ = 1
2 (1+2) 2(3) 6
If (1+2) is part of the dividend then we can use equation B wherein the answer will be
6
-------- * (1+2) = 3 * (1+2) = 3*3 = 9
2
The full mnemonic is PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition and Subtraction).
First simplify parenthesis: 1 + 2 is 3, hence the number equation becomes 6/2(3)
Then, multiplication: 6 times 3 is 18, hence the equation becomes 18/2
Then division: 18 divided by 2 is 9, hence the result is 9.
In the above procedure, division of 6 by 2 can be done before multiplication, since multiplication and division have the same order, as do addition and subtraction.
I will use the formula of BODMAS to solve it.
B=Bracket
O=Or
D=Division
M=Multiplication
A=Addition
S=Subtraction
So, here it goes...
6/2(1+2)
=6/2(3)
=3(3)
=9
The answer is 9
Here we will use BODMAS rule to solve the problem. BODMAS stands for bracket ,off,division,multiply,add,substract. So here we will first simplify brackets so
6/2(1+2) = 6/2*3 = 3*3 = 9
We solve this question by BODMAS method we start solving first we solve bracket then division and then multiplication
6/2(1+2) =6/2(3)
=3*3
=9
so, answer is 9
Kindly ignore the misplaced number on the 8th paragraph; it should be written like this...thanks
6 6 6
--------- = ---------- = ------ = 1
2 (1+2) 2(3) 6
It uses PEMDAS ( Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction)
X = 6/2 (1+2)
= 6/2(3)
= 6/6
X = 1
Using bodmas we start with brackets [1+2]=3 then 6/2=3 so the equation becomes 3[3]=3*3=9
