What is the value of $(2 + 3)^2 - 4$?
7
6
21
9
Explanation
Follow PEMDAS. Parentheses: $2 + 3 = 5$. Exponents: $5^2 = 25$. Addition/Subtraction: $25 - 4 = 21$.
What is the value of $4 \times 3^2 + 5$?
41
56
29
149
Explanation
Follow PEMDAS. Exponents: $3^2 = 9$. Multiplication: $4 \times 9 = 36$. Addition: $36 + 5 = 41$.
What is the value of $18 \div 3^2 + 6$?
42
12
9
8
Explanation
Follow PEMDAS. Exponents: $3^2 = 9$. Division: $18 \div 9 = 2$. Addition: $2 + 6 = 8$.
What is the value of $2^3 + (10 - 4) \times 2$?
28
20
18
16
Explanation
Follow PEMDAS. Exponents: $2^3 = 8$. Parentheses: $10 - 4 = 6$. Multiplication: $6 \times 2 = 12$. Addition: $8 + 12 = 20$.
What is the value of $(3+2)^2 - 4$?
3
21
9
25
Explanation
Follow PEMDAS: 1) Parentheses: $(3+2)=5$. 2) Exponents: $5^2=25$. 3) Multiplication/Division: none. 4) Addition/Subtraction: $25-4=21$.
What is the value of $2^3 + 6 \div 3 \times 2$?
9
10
20
12
Explanation
Follow PEMDAS: 1) Exponents: $2^3=8$. 2) Multiplication/Division left to right: $6\div 3=2$, then $2\times 2=4$. 3) Addition: $8+4=12$.
What is the value of $5 \times (2^2 + 3)$?
35
23
125
160
Explanation
Follow PEMDAS: 1) Exponents: $2^2=4$. 2) Parentheses: $4+3=7$. 3) Multiplication: $5\times 7=35$.
What is the value of $7 + 3^2 \times 2$?
32
19
25
43
Explanation
Follow PEMDAS: 1) Exponents: $3^2=9$. 2) Multiplication: $9\times 2=18$. 3) Addition: $7+18=25$.
What is the value of $2^3 + 4 \times 3$?
36
18
30
20
Explanation
Apply PEMDAS. 1) Exponents: $2^3 = 8$. 2) Multiplication: $4 \times 3 = 12$. 3) Addition: $8 + 12 = 20$. So the value is $20$.
What is the value of $(2^3 + 6) \div 2$?
7
11
6
14
Explanation
Use PEMDAS. 1) Parentheses first; inside, do the exponent: $2^3 = 8$, then add: $8 + 6 = 14$. 2) Division: $14 \div 2 = 7$. So the value is $7$.
