Question

27-[18-{16-(5-4-1)}]

Answer 1

27-[18-{16-(5-4-1)}]
= 27-[18-(16-( 5-5 ) ]
=27-[18( 16-0) ]
= 27- [18-( 16)]
= 27 - (18-16)
=27- 2
= 25 ...is the answer...

Answer 2

Answer:

The simplified value of the expression is 25.

Step-by-step explanation:

Recall the BODMAS rule,

B = Brackets         O = Order off           D = Division

M = Multiplication     A = Addition        S = Subtraction

Step 1 of 1

Consider the given expression as follows:

27 - [18 - {$16$ - (5 - 4 - 1)}]

First, simplify the expression inside the round brackets as follows:

⇒ 27 - [18 - {16 - (0)}] (Since 5 - 4 - 1 = 5 - $5$ = 0)

⇒ 27 - [18 - {16 - $0$}]

Second,

Simplify the expression inside the curly bracket as follows:

⇒ 27 - [$18$ - {16}] (Since 16 - $0$ = 16)

⇒ 27 - [18 - 16]

Third,

Simplify the expression inside the square bracket as follows:

⇒ 27 - [$2$] (As 18 - 16 = 2)

⇒ 27 - 2

Finally, compute the difference of the numbers 27 and 2, we get

⇒ 25

Therefore, the simplified value of the expression is 25.
