Question

((-6) + 7 - 3) x 2 divided by 4. Order of operations? I think the answer is -1.

Answer 1

-1

Explanation:

The order of operation (PEMDAS) states that:

• P - Parenthesis
• E - Exponents
• M - Multiplication
• D - Division
• A - Addition
• S - Subtraction

Given expression:

• [{(-6) + 7 - 3} x 2] ÷ 4

We can see that "-6" is the integer that is inside the parenthesis "( )". Therefore, we can open the parenthesis "( )".

• ⇒ [{-6 + 7 - 3} x 2] ÷ 4

Simplify the expression inside the curvy brackets "{ }" using PEMDAS.

• ⇒ [{1 - 3} x 2] ÷ 4 [PEMDAS]
• ⇒ [{-2} x 2] ÷ 4 [PEMDAS]

Now we can open the curvy brackets "{ }".

• ⇒ [-2 x 2] ÷ 4

Simplify the expression inside the long brackets "[ ]" using PEMDAS.

• ⇒ [-4] ÷ 4

Finally, open the long brackets "[ ]" and simplify the expression obtained.

• ⇒ -4 ÷ 4
• ⇒ -1
