Question

(20 x 8) x 3 -45 / 5 - 7 X (30 -6 x 5) =

Answer 1

here's the step-by-step calculation:

(20 x 8) x 3 - 45 / 5 - 7 x (30 - 6 x 5) =

First, let's simplify the parentheses:
(20 x 8) x 3 - 45 / 5 - 7 x (30 - 30) =

Next, let's simplify the multiplication and division:
160 x 3 - 45 / 5 - 7 x 0 =

Now, let's do the remaining multiplication and division:
480 - 9 - 0 =

Finally, let's do the subtraction:
471

So, the answer is 471.

Answer 2

To solve the expression, use the order of operations (PEMDAS) to simplify each step and arrive at the final answer of 471.

Step-by-step explanation:

To solve the expression (20 x 8) x 3 - 45 / 5 - 7 x (30 - 6 x 5), we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

1. First, we simplify the expression inside the parentheses: (30 - 6 x 5) = (30 - 30) = 0.
2. Next, we perform the multiplication: (20 x 8) x 3 = 160 x 3 = 480.
3. Then, we divide: 45 / 5 = 9.
4. After that, we perform the multiplication: 7 x 0 = 0.
5. Finally, we subtract: 480 - 9 - 0 = 471.

So, the result of the expression is 471.
