72-5(13+2)*5=

(72 - 55) * 5 = 85

72-5(13+2)*5=

(72 - 55) * 5 = 85

How did you arrive to 55? Please explain

I goofed. Sorry. Let's try it again.

72-5(13+2)*5=

(72 - 75)* 5 = -15

Eh?

72 - 5(13+2)*5
72 - 5(15)*5
72 - 75*5
72 - 375
-303

Order Of Operation:

1. Parenthesis
2. Multiplication
3. Subtraction

72 - 5(13 + 2)* 5
(15)
5(15)* 5
75 * 5
375
72 - 375 = -303

To solve the mathematical expression 72-5(13+2)×5, we need to follow the order of operations (also known as PEMDAS or BODMAS), which states that we should perform operations inside parentheses first, then any exponential (power) operations, followed by multiplication and division (from left to right), and finally addition and subtraction (from left to right).

Let's break down the expression step by step:

1. Start by evaluating the expression inside the parentheses:
13 + 2 = 15

Now, the expression becomes 72 - 5(15) × 5.

2. Next, perform the multiplication:
5 × 15 = 75

The expression becomes 72 - 75 × 5.

3. Finally, calculate the remaining multiplication and subtraction:
75 × 5 = 375

72 - 375 = -303

Therefore, the solution to the expression 72 - 5(13+2) × 5 is -303.
