Find the value of the expression

-128/(4)2+6-1

To find the value of the expression -128/(4)2+6-1, we need to follow the correct order of operations, also known as the PEMDAS rule:

P - Parentheses (simplify expressions within parentheses first)
E - Exponents (evaluate any expressions with exponents)
MD - Multiplication and Division (perform any multiplication or division from left to right)
AS - Addition and Subtraction (perform any addition or subtraction from left to right)

Let's break down the expression step by step:

1. Simplify any expressions within parentheses: (4)2 = 16

So the expression becomes: -128/16 + 6 - 1

2. Perform any division: -128/16 = -8

The expression becomes: -8 + 6 - 1

3. Perform any addition and subtraction: -8 + 6 = -2, then -2 - 1 = -3

Therefore, the value of the expression -128/(4)2+6-1 is -3.
