22+6[(14-5)÷3(17-14)]

I got 76 and every calculator I use says 76 but in the back of the book it says the answer is 28. Am I missing something or could it be a typo?
My work:
22+6[(14-5)÷3(17-14)]
22+6[(9)÷3(3)]
22+6 [(3)(3)]
22+6(9)
22+54 = 76

The simplification of the expression is 28. The mistake in your calculation occurred in step 3.

What is the process involved in simplifying expression involving brackets?

TO simplify expressions involving brackets, we use a common method called BODMAS (Brackets, Of, Division, Multiplication, Addition, and Subtraction).

This means that we will first solve the expression in brackets first, followed by division, multiplication, addition, and subtraction as the case may be.

Now, from the given information, we have:
= 22+6[(14-5)÷3(17-14)]

solving parameters in the bracket first, we have:
= 22 + 6[(9) ÷3(3)]

= 22 + 6[(9) ÷9]          

  • The above step is where you missed it from your calculation, you must first open all brackets within brackets before solving them.

= 22 + 6[(9) ÷9]    

= 22 + 6[ 1]

= 22 + 6

= 28
