Answer:
(16 - 8 × 2 ÷ 4 + 6) ÷ 3 = 6
Step-by-step explanation:
The given expression is (16 - 8 × 2 ÷ 4 + 6) ÷ 3
We will solve this expression by using BODMAS rule,
B - Bracket (Parenthesis)
O - Order (exponents)
D - Division
M - Multiplication
A - Addition
S - Subtraction
(16 - × 2 ÷ 4 + 6) ÷ 3
We will solve the expression inside the parenthesis first followed up by the exponents,
(16 - × 2 ÷ 4 + 6)
= (16 - 8 × 2 ÷ 4 + 6)
Then Divide,
= (16 - 8 × + 6)
Then multiply,
= (16 - 4 + 6)
Further addition,
= (22 - 4 )
At last subtract,
= (18)
Now put the solution of the parentheses in the expression,
= (18) ÷ 3
= 6
Therefore, solution of the given expression will be 6.
