Calculation Explanation

To solve the given expression 2980*(423+168)-(57*17-209)*6:3+533700:9, let's break it down step by step:

1. First, we need to calculate the expression inside the parentheses (423+168), which equals 591. 2. Next, we calculate the expression inside the parentheses (57*17-209), which equals -2. 3. Now, we can substitute the calculated values into the main expression: 2980*591-(-2)*6:3+533700:9.

Order of Operations

To solve this expression, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

1. Parentheses: We have already calculated the expressions inside the parentheses. 2. Multiplication and Division: We perform these operations from left to right. 3. Addition and Subtraction: We perform these operations from left to right.

Calculation Steps

Let's calculate the expression step by step:

1. 2980*591 equals 1,759,380. 2. -2*6 equals -12. 3. -12:3 equals -4. 4. 533700:9 equals 59,300.

Now, we can substitute the calculated values into the main expression:

1,759,380 - (-4) + 59,300

To simplify further, we can remove the double negative:

1,759,380 + 4 + 59,300

Adding the numbers together:

1,818,684

Therefore, the result of the expression 2980*(423+168)-(57*17-209)*6:3+533700:9 is 1,818,684.
