Consider the expression [15+(−5)]+62 . What is the result of the first simplification that would need to take place, according to the order of operations?

Answer 1

To simplify the expression \([15 + (-5)] + 62\), we first focus on simplifying the expression inside the brackets, as this is the first step according to the order of operations (parentheses first).

The expression inside the brackets is \(15 + (-5)\).

Calculating this:

\[ 15 + (-5) = 15 - 5 = 10 \]

After this simplification, the expression becomes:

\[ 10 + 62 \]

So the first simplification that takes place is \(15 + (-5) = 10\).
