$\small{ \bold{ \green{answer}}}$

78 + ( - 15 × 12 ÷ 2 ) = - 12

the answer is - 12

Answer 2

Solution :

78 + ( - 15 × 12 ÷ 2)

To solve this, let's use BODMAS rule :

• B = Brackets
• O = Order or power
• D = Division
• M = Multiplication
• A = Addition
• S = Subtraction

The BODMAS rule states we should calculate the Brackets first :

⟹ 78 + ( - 15 × 12 ÷ 2) = 78 + (- 15 × 12 ÷ 2)

Then solve the Orders or powers but there are no orders or powers, So let's move forward

Then solve any Division :

⟹ 78 + ( - 15 × 12 ÷ 2) = 78 + (- 15 × 6)

Then solve any Multiplication :

⟹ 78 + ( - 15 × 12 ÷ 2) = 78 + (- 90)

Now, plus(+) Minus(-) = Minus(-) :

⟹ 78 + ( - 15 × 12 ÷ 2) = 78 - 90

And finally solve any Addition or Subtraction :

⟹ 78 + ( - 15 × 12 ÷ 2) = - 12

Hence, 78 + ( - 15 × 12 ÷ 2) = - 12.
