Order of Operations - SSAT Middle Level: Quantitative

$3$. Parentheses take precedence, so compute $3 \times 2$ first before dividing 18 by the result.

$10$. Multiplication and division are performed left to right before addition, so compute $20 \div 5$ and $2 \times 3$ separately, then add the results.

$16$. Exponents precede subtraction, so compute $5^2$ and $3^2$ before subtracting.

$18$. Parentheses take precedence, so compute $2^3 + 1$ before multiplying by 2.

$9$. Exponents precede addition, so evaluate $2^3$ before adding 1.

Parentheses, exponents, multiply/divide, add/subtract (left to right). The order of operations follows PEMDAS: parentheses first, then exponents, multiplication and division from left to right, and addition and subtraction from left to right.

Compute $24 \div 6$ first, then multiply by $2$. Multiplication and division have the same precedence and are evaluated from left to right, so perform division before multiplication in this expression.

Compute $10 - 3$ first, then add $4$. Addition and subtraction have the same precedence and are evaluated from left to right, so perform subtraction before addition in this expression.

$11$. Multiplication precedes addition in the order of operations, so compute $4 \times 2$ before adding 3.

$14$. Parentheses take precedence, so evaluate $3 + 4$ first before multiplying by 2.

$12$. Division and multiplication are performed left to right, so divide 18 by 3 before multiplying by 2.

$7$. Exponents precede multiplication, which precedes addition, so compute $0^2$ first, then multiply by 3, and add to 7.

$13$. Exponents precede multiplication, which precedes addition, so compute $5^1$ first, then multiply by 2, and add to 3.

$10$. Parentheses and brackets take precedence, so evaluate innermost $7 - 3$ first, then add 1, and multiply by 2.

$7$. Multiplication precedes addition, so compute $\frac{1}{2} \times 8$ before adding 3.

$\frac{11}{2}$. Parentheses take precedence, so compute $8 + 3$ before multiplying by $\frac{1}{2}$.

$0$. Parentheses take precedence, so compute $2 + 1$ first, then multiply by 3 before subtracting from 9.

$5$. Parentheses take precedence, so compute $4 + 3$ before subtracting from 12.

$64$. Parentheses take precedence, so compute $16 \div 2$ before squaring the result.

$18$. Parentheses take precedence, so evaluate $9 - 3$ and $2 + 1$ separately before multiplying the results.

$11$. Addition and subtraction are performed left to right, so subtract 4 from 12 before adding 3.

$-6$. Exponents precede multiplication, which precedes subtraction, so compute $2^2$ first, then multiply by 3, and subtract from 6.

$4$. Exponents precede division, so compute $2^2$ before dividing 16 by the result.

$9$. Parentheses take precedence, so compute $7 - 3$ first, then multiply by 2 before adding 1.
