Flashcard 19 - Mathematics Flashcard Set for the HESI Exam

1. Evaluate the multiplication inside the parentheses.
2. Simplify the exponent.
3. Add and subtract.

According to the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), we first evaluate the parentheses:

\[5 \times 2 = 10\]

Then, we compute the exponent:

\[9^2 = 81\]

Finally, we do addition and subtraction:

\[= 4 - 10 +81\] \[= 75\]

Following this order ensures accurate computation.
