Problem

Evaluate the expression
\$ (5^2) - (3 \times 2 + 4) \div 2 \$

2

Step

Given expression

\$ (5^2) - (3 \times 2 + 4) \div 2 \$

3

Hint

To evaluate the expression, let’s follow the PEMDAS rule:

Parentheses
Exponents
Multiplication and Division (from left to right)
Addition and Subtraction (from left to right)

4

Step

Evaluate the expression inside the parentheses

\$ 3 \times 2 = 6 \$

6 + 4 = 10

5

Step

So, the expression becomes

\$ 5^2 -10 \div 2\$

6

Step

Evaluate the exponent

\$ 5^2 \$ = 25

7

Step

So, the expression becomes

\$ 25 - 10 \div 2 \$

8

Step

Perform the division

\$ 10/2 \$ = 5

9

Step

Perform the subtraction:

25 - 5 = 20

10

Solution

Therefore, the value of the expression is 20.
