Evaluate the expression: 2(50 - 4 · 3²)

• 28

• 76

• 84

• 92

Answer explanation

To evaluate the expression 2(50−4⋅3²), follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, solve the exponent 3², which equals 9.

Next, multiply 4 by 9, resulting in 36.

Then, subtract 36 from 50, which equals 14.

Finally, multiply 14 by 2, resulting in 28.

So, 2(50−4⋅3²)=28

Evaluate 9 + 12 ÷ 3 + (15 – 4) · 2

• 35

• 36

• 29

• 42

Answer explanation

To evaluate the expression 9+12÷3+(15−4)⋅29+12÷3+(15−4)⋅2, follow the order of operations:

1. Parentheses

2. Exponents

3. Multiplication and Division (from left to right)

4. Addition and Subtraction (from left to right)

First, solve the expression inside the parentheses:

15−4=11

Next, perform the multiplication inside the parentheses:

11⋅2=22

Now, deal with the division:

12÷3=4

Next, perform the additions:

9+4+22

Finally, add the numbers together:

9+4+22=35

So, 9+12÷3+(15–4)⋅2=35

Jada and Toby each evaluated 14 – 4 + (3 – 1) · 2. Consider Jada's work and Toby's work. Who correctly evaluated the expression? ​ (a)  

• Jada
• Toby
• They are both wrong
• They are both correct

Jada and Toby each evaluated 14 – 4 + (3 – 1) · 2

Which explanation of the correct evaluation of the expression is best?

• Jada correctly evaluated the expression because she evaluated inside the parenthesis first. Then she multiplied, added, and subtracted.

• Toby correctly evaluated the expression because he evaluated from left to right for all of the operations.

• Toby correctly evaluated the expression because he evaluated inside the parenthesis first. Then he multiplied, added, and subtracted. both wrong

• Jada correctly evaluated the expression because he evaluated from left to right for all of the operations.
