PEMDAS (order of operations rules) require that we perform operations in a certain order: anything inside parentheses first, followed by any exponentiation, followed by mult. and div., finally followed by addition and subtraction.
Thus, we must evaluate 5+8÷4-1 first, as it's inside parentheses. Focusing on the division first, we get 5+8÷4-1 = 5 + 2 - 1, or 6.
Then we have 5 - [6], which comes out to -1.

How many nickles are in 60 cents? 12, because 5 times 12 is 60.
The greatest
possible error when measuring to the nearest quarter of an inch is how the
reader reads the measurement. Sometimes, we base our answers to what we can see
and what we see may be different from others.
